Hitachi Global Storage Technologies, the San Jose, California-based joint venture of Japanese storage vendor Hitachi and U.S. technology giant IBM, has set a new record for storage density at 230 gigabits per square inch (Gb/in²). The company has developed technology to implement a recording method known as perpendicular recording, which allowed the increase in density above the current ~130 Gb/in² limit.

Techworld claims there is a race between Hitachi and Toshiba for who will get the first drives to market which use the technology. According to Hitachi, they expect, “to ship [their] first perpendicular recording product in 2005 on a 2.5-inch hard drive”. Toshiba is also planning to ship a drive in 2005 that uses perpendicular recording.

According to Techworld, Toshiba will ship an 80 GB, 1.8″ drive in 2005. Toshiba’s 1.8″ drives are used in portable electronic devices such as Apple’s iPod, which is currently available in sizes 60 GB and smaller.

While all commercially available hard drives to date use longitudinal recording, perpendicular recording has roots in research done in academic circles over 100 years ago.

Hitachi Tech has produced a Flash animation that explains the rudiments of perpendicular recording in a music-video style.

Inspired by the 1970s Schoolhouse Rock series of educational animation shorts, the flash movie features whimsical moments with data bits and disk platters that speak and sing (not possible with today’s technology), it also contains realistic details. Of no importance to the viewer, but perhaps of interest to some, the animation shows Texas Instruments’ UC5608DWP chips visible briefly in the background. While TI’s UC5608DWP 18-line SCSI terminator chips have been made obsolete by the new UCC5618, the chips are indeed designed for use in hard drives.

David Edward “Chip” Reese, an American professional poker player, died on December 4, 2007, at the age of 56. Reese died in his sleep at his Las Vegas, Nevada home from the effects of pneumonia.

Reese is generally considered a legend in the world of poker. In 1991, he became the youngest living player to be inducted into the Poker Hall of Fame. His last major win came at the 2006 World Series of Poker, where he won US$1,784,640 in the HORSE event.

“Chip Reese was probably the most successful poker player in history,” said Mike Sexton. “Chip has always been admired by players for his success, his demeanor at the table.”

“I knew him for 35 years, I never saw him get mad or raise his voice,” Doyle Brunson said. “He had the most even disposition of anyone I’ve ever met. He’s certainly the best poker player that ever lived.”

His career spanned multiple decades and Reese made the majority of his money when poker gained publicity through national television exposure starting around the turn of the century. Though he never won the “Main Event” in Texas hold’em at the World Series of Poker, Reese was very successful.

“He was a family man like no one else in poker,” said fellow poker professional Barry Greenstein. “No matter what the situation was, if his kids had something going on — a baseball game, a recital, whatever — he would quit to go to it.”

“Probably a lot of us were jealous of him that he was able to do that — that he had done well enough in poker, that he could always take time off of poker to be involved with his kids,”Greenstein added.

Reese earned a degree from Dartmouth College and was accepted to law school at Stanford University, but he was drawn by the lure of big winnings and chose instead to earn his living at the poker table. He once told a reporter that law “doesn’t have the same monetary incentive as poker.”

The New Zealand Government on Thursday announced the creation of a new public holiday, Matariki. Matariki marks the beginning of the M?ori New Year, which coincides with the rising of the star cluster Pleiades, known as Matariki in the M?ori language.

At Waitangi, New Zealand Prime Minister Jacinda Ardern said “This will be a day to acknowledge our nation’s unique, shared identity, and the importance of tikanga M?ori. It’s going to be something very special, and something uniquely New Zealand.” Ardern also said the new holiday would break up the over-4 month gap between public holidays in June and October.

The date of the Matariki holiday is not consistent from year to year, as it follows Maramataka, the M?ori lunar calendar, but would likely always fall on a Monday or Friday according to Ardern. A Matariki advisory group has been established, with M?ori Crown Relations — Te Arawhiti — Minister Kelvin Davis explaining that the purpose of the group is “to provide advice on future dates of the public holiday, how it should be celebrated and to support the development of resources to educate the public on Matariki and the celebrations”. The first Matariki holiday is scheduled for Friday, June 24 of next year.

Ardern’s Labour Party made the Matariki holiday an election promise, and won last year’s general election with a majority. This result was the best for any party since New Zealand’s 1996 adoption of a mixed-member proportional system.

This is not the first attempt to make Matariki a public holiday. In 2009, M?ori Party Member of Parliament Rahui Katene introduced legislation to create a Matariki public holiday. While it was supported by the then-opposition Labour Party, the governing National Party did not support it, and it was defeated with 59 votes in favour and 63 votes against.

The International Olympic Committee (IOC) has given the late Jack Poole their highest honour, The Olympic Order, according to a report by the Vancouver Sun.

Mr. Poole, one of the people behind the bid by Vancouver to host the 2010 Olympic Winter Games, passed away on October 23 after losing a fight with pancreatic cancer.

The CEO of the Vancouver organizing committee (VANOC), John Furlong, was quoted as saying “Jack Poole is truly deserving of the tremendous honour of the Olympic Order in recognition of his enormous contribution to the 2010 Games,” also stating that further comment will be made when the IOC makes a formal announcement of the award.

This marks the second award that has posthumously been given to Poole, having been awarded the Canadian Olympic Order by the Canadian Olympic Committee (COC) earlier in the month, with word that he will also be inducted to the Canadian Olympic Hall of Fame.

A new historic physics record has been set by scientists for exceedingly small writing, opening a new door to computing‘s future. Stanford University physicists have claimed to have written the letters “SU” at sub-atomic size.

Graduate students Christopher Moon, Laila Mattos, Brian Foster and Gabriel Zeltzer, under the direction of assistant professor of physics Hari Manoharan, have produced the world’s smallest lettering, which is approximately 1.5 nanometres tall, using a molecular projector, called Scanning Tunneling Microscope (STM) to push individual carbon monoxide molecules on a copper or silver sheet surface, based on interference of electron energy states.

A nanometre (Greek: ?????, nanos, dwarf; ?????, metr?, count) is a unit of length in the metric system, equal to one billionth of a metre (i.e., 10^-9 m or one millionth of a millimetre), and also equals ten Ångström, an internationally recognized non-SI unit of length. It is often associated with the field of nanotechnology.

“We miniaturised their size so drastically that we ended up with the smallest writing in history,” said Manoharan. “S” and “U,” the two letters in honor of their employer have been reduced so tiny in nanoimprint that if used to print out 32 volumes of an Encyclopedia, 2,000 times, the contents would easily fit on a pinhead.

In the world of downsizing, nanoscribes Manoharan and Moon have proven that information, if reduced in size smaller than an atom, can be stored in more compact form than previously thought. In computing jargon, small sizing results to greater speed and better computer data storage.

“Writing really small has a long history. We wondered: What are the limits? How far can you go? Because materials are made of atoms, it was always believed that if you continue scaling down, you’d end up at that fundamental limit. You’d hit a wall,” said Manoharan.

In writing the letters, the Stanford team utilized an electron‘s unique feature of “pinball table for electrons” — its ability to bounce between different quantum states. In the vibration-proof basement lab of Stanford’s Varian Physics Building, the physicists used a Scanning tunneling microscope in encoding the “S” and “U” within the patterns formed by the electron’s activity, called wave function, arranging carbon monoxide molecules in a very specific pattern on a copper or silver sheet surface.

“Imagine [the copper as] a very shallow pool of water into which we put some rocks [the carbon monoxide molecules]. The water waves scatter and interfere off the rocks, making well defined standing wave patterns,” Manoharan noted. If the “rocks” are placed just right, then the shapes of the waves will form any letters in the alphabet, the researchers said. They used the quantum properties of electrons, rather than photons, as their source of illumination.

According to the study, the atoms were ordered in a circular fashion, with a hole in the middle. A flow of electrons was thereafter fired at the copper support, which resulted into a ripple effect in between the existing atoms. These were pushed aside, and a holographic projection of the letters “SU” became visible in the space between them. “What we did is show that the atom is not the limit — that you can go below that,” Manoharan said.

“It’s difficult to properly express the size of their stacked S and U, but the equivalent would be 0.3 nanometres. This is sufficiently small that you could copy out the Encyclopaedia Britannica on the head of a pin not just once, but thousands of times over,” Manoharan and his nanohologram collaborator Christopher Moon explained.

The team has also shown the salient features of the holographic principle, a property of quantum gravity theories which resolves the black hole information paradox within string theory. They stacked “S” and the “U” – two layers, or pages, of information — within the hologram.

The team stressed their discovery was concentrating electrons in space, in essence, a wire, hoping such a structure could be used to wire together a super-fast quantum computer in the future. In essence, “these electron patterns can act as holograms, that pack information into subatomic spaces, which could one day lead to unlimited information storage,” the study states.

The “Conclusion” of the Stanford article goes as follows:

According to theory, a quantum state can encode any amount of information (at zero temperature), requiring only sufficiently high bandwidth and time in which to read it out. In practice, only recently has progress been made towards encoding several bits into the shapes of bosonic single-photon wave functions, which has applications in quantum key distribution. We have experimentally demonstrated that 35 bits can be permanently encoded into a time-independent fermionic state, and that two such states can be simultaneously prepared in the same area of space. We have simulated hundreds of stacked pairs of random 7 times 5-pixel arrays as well as various ideas for pathological bit patterns, and in every case the information was theoretically encodable. In all experimental attempts, extending down to the subatomic regime, the encoding was successful and the data were retrieved at 100% fidelity. We believe the limitations on bit size are approxlambda/4, but surprisingly the information density can be significantly boosted by using higher-energy electrons and stacking multiple pages holographically. Determining the full theoretical and practical limits of this technique—the trade-offs between information content (the number of pages and bits per page), contrast (the number of measurements required per bit to overcome noise), and the number of atoms in the hologram—will involve further work.—Quantum holographic encoding in a two-dimensional electron gas, Christopher R. Moon, Laila S. Mattos, Brian K. Foster, Gabriel Zeltzer & Hari C. Manoharan

The team is not the first to design or print small letters, as attempts have been made since as early as 1960. In December 1959, Nobel Prize-winning physicist Richard Feynman, who delivered his now-legendary lecture entitled “There’s Plenty of Room at the Bottom,” promised new opportunities for those who “thought small.”

Feynman was an American physicist known for the path integral formulation of quantum mechanics, the theory of quantum electrodynamics and the physics of the superfluidity of supercooled liquid helium, as well as work in particle physics (he proposed the parton model).

Feynman offered two challenges at the annual meeting of the American Physical Society, held that year in Caltech, offering a $1000 prize to the first person to solve each of them. Both challenges involved nanotechnology, and the first prize was won by William McLellan, who solved the first. The first problem required someone to build a working electric motor that would fit inside a cube ¹/₆₄ inches on each side. McLellan achieved this feat by November 1960 with his 250-microgram 2000-rpm motor consisting of 13 separate parts.

In 1985, the prize for the second challenge was claimed by Stanford Tom Newman, who, working with electrical engineering professor Fabian Pease, used electron lithography. He wrote or engraved the first page of Charles Dickens’ A Tale of Two Cities, at the required scale, on the head of a pin, with a beam of electrons. The main problem he had before he could claim the prize was finding the text after he had written it; the head of the pin was a huge empty space compared with the text inscribed on it. Such small print could only be read with an electron microscope.

In 1989, however, Stanford lost its record, when Donald Eigler and Erhard Schweizer, scientists at IBM’s Almaden Research Center in San Jose were the first to position or manipulate 35 individual atoms of xenon one at a time to form the letters I, B and M using a STM. The atoms were pushed on the surface of the nickel to create letters 5nm tall.

In 1991, Japanese researchers managed to chisel 1.5 nm-tall characters onto a molybdenum disulphide crystal, using the same STM method. Hitachi, at that time, set the record for the smallest microscopic calligraphy ever designed. The Stanford effort failed to surpass the feat, but it, however, introduced a novel technique. Having equaled Hitachi’s record, the Stanford team went a step further. They used a holographic variation on the IBM technique, for instead of fixing the letters onto a support, the new method created them holographically.

In the scientific breakthrough, the Stanford team has now claimed they have written the smallest letters ever – assembled from subatomic-sized bits as small as 0.3 nanometers, or roughly one third of a billionth of a meter. The new super-mini letters created are 40 times smaller than the original effort and more than four times smaller than the IBM initials, states the paper Quantum holographic encoding in a two-dimensional electron gas, published online in the journal Nature Nanotechnology. The new sub-atomic size letters are around a third of the size of the atomic ones created by Eigler and Schweizer at IBM.

A subatomic particle is an elementary or composite particle smaller than an atom. Particle physics and nuclear physics are concerned with the study of these particles, their interactions, and non-atomic matter. Subatomic particles include the atomic constituents electrons, protons, and neutrons. Protons and neutrons are composite particles, consisting of quarks.

“Everyone can look around and see the growing amount of information we deal with on a daily basis. All that knowledge is out there. For society to move forward, we need a better way to process it, and store it more densely,” Manoharan said. “Although these projections are stable — they’ll last as long as none of the carbon dioxide molecules move — this technique is unlikely to revolutionize storage, as it’s currently a bit too challenging to determine and create the appropriate pattern of molecules to create a desired hologram,” the authors cautioned. Nevertheless, they suggest that “the practical limits of both the technique and the data density it enables merit further research.”

In 2000, it was Hari Manoharan, Christopher Lutz and Donald Eigler who first experimentally observed quantum mirage at the IBM Almaden Research Center in San Jose, California. In physics, a quantum mirage is a peculiar result in quantum chaos. Their study in a paper published in Nature, states they demonstrated that the Kondo resonance signature of a magnetic adatom located at one focus of an elliptically shaped quantum corral could be projected to, and made large at the other focus of the corral.

From the middle of July, Sony Corporation refreshed their senior laptop brand VAIO from “Video Audio Integrated Operation” to “Visual Audio Intelligent Organizer”. According to Sony Taiwan Limited, this refreshment is an attempt to relocate the laptop consuming market for business and entertainment factors.

In the “VAIO Experience 2008” press conference in Europe, Sony promoted their new product series for different populations including BZ for business, FW for home entertainment, Z for ultra-slim, and SR for complex applications.

Different with past series, Sony added “Clear Bright” screening technology for high-definition display, and “full-carbon production” features. BD-burning and Intel Centrino 2 processing technologies will be featured in all the new models. For security issue, Sony also embedded fingerprint system to prevent personal data to be stolen. Continued from TZ series, innovative designs including “Green Power Button”, “Situational Switch” are also added in newly-launched series.

“Due to consuming market differences, Sony only promoted BZ series in Europe and America but not included Asia. Although the TICA Show in Taipei will be different, functionality will be the greatest issue when a consumers choose a notebook [computer] before buying.” addressed by executives from Sony Taiwan Limited, during the “VAIO Experience 2008” press conference in Taiwan.

Dell Inc., a global leader in computer hardware manufacturing and sales, announced yesterday that it will delay filing of its annual performance report, the Form 10-K, required for compliance with U.S. Securities and Exchange Commission (SEC) and Nasdaq listing rules.

In a press release, Dell explained that an audit committee of the company’s board of directors is carrying out an investigation into accounting and financial reporting issues. The company stated that it would delay filing of the 10-K since the investigation had not been completed.

The internal investigation has found evidence of accounting errors, misconduct, and deficiencies in areas of financial control.

The chairman of Dell’s audit committee, Thomas Luce III, indicated that the delay in filing would extend past the April 3, 2007 deadline as well as an April 18, 2007 extension date. “As we move toward the conclusion of our investigation, we are committing the time and resources required to ensure a thorough and comprehensive review and resolution of all identified issues and the implementation of appropriate remedial measures,” said Luce.

The investigation is to determine whether the restatement of any financial disclosures are warranted, based on the accounting errors identified. The probe will also assess whether there are deficiencies in Dell’s internal control over financial reporting.
