Start-up to release 'stone-like' optical disc that lasts forever

New optical disc aims for consumer market first, then corporate archives

By Lucas Mearian

From: Computerworld

Start-up Millenniata and Hitachi-LG Data Storage plan to soon release a new optical disc and read/write player that will store movies, photos or any other data forever. The data can be accessed using any current DVD or Blu-ray player.

Millenniata calls the product the M-Disc, and the company claims you can dip it in liquid nitrogen and then boiling water without harming it. It also has a U.S. Department of Defense (DoD) study backing up the resiliency of its product compared to other leading optical disc competitors.

Millenniata CEO Scott Shumway would not disclose what material is used to produce the optical discs, referring to it only as a "natural" substance that is "stone-like."

The M-Disc
Millenniata's M-Disc is made of a stone-like substance that the company claims does not degrade over time.

Like DVDs and Blu-ray discs, the M-Disc platters are made up of multiple layers of material. But unlike the former, there is no reflective or die layer. Instead, during the recording process a laser "etches" pits onto the substrate material.

"Once the mark is made, it's permanent," Shumway said. "It can be read on any machine that can read a DVD. And it's backward compatible, so it doesn't require a special machine to read it - just a special machine to write it."

While Millenniata has partnered with Hitachi-LG Data Storage for the initial launch of an M-Disc read-write player in early October, Shumway said any DVD player maker will be able to produce M-Disc machines by simply upgrading their product's firmware.

Millenniata said it has also proven it can produce Blu-ray format discs with its technology - a product it plans to release in future iterations. For now, the platters store the same amount of data as a DVD: 4.7GB. However, the discs write at only 4x or 5.28MB/sec, half the speed of today's DVD players.

"We feel if we can move to the 8X, that'd be great, but we can live with the four for now," Shumway said, adding that his engineers are working on upping the speed of recording.

Millenniata is also targeting the long-term data archive market, saying archivists will no longer have to worry about controlling the temperature or humidity of a storage room. "Data rot happens with any type of disc you have. Right now, the most permanent technology out there for storing information is a paper and pencil -- until now," Shumway said.

In 2009, the Defense Department's Naval Air Warfare Weapon's Division facility at China Lake, Calif. was interested in digitizing and permanently storing information. So it tested Millenniata's M-Disc against five other optical disc vendors: Delkin Devices, Mitsubishi, JVC, Verbatim and MAM-A.

"None of the Millenniata media suffered any data degradation at all. Every other brand tested showed large increases in data errors after the stress period. Many of the discs were so damaged that they could not be recognized as DVDs by the disc analyzer," the department's report states.

Recordable optical media such as CDs, DVDs and Blu-ray discs are made of layers of polycarbonate glued together. One layer of the disk contains a reflective material and a layer just above it incorporates an organic transparent dye. During recording, a laser hits the die layer and burns it, changing the dye from transparent to opaque creating bits of data. A low power laser then can read those bits by either passing through the transparent dye layer to the reflective layer or being absorbed by the pits.

Over long periods of time, DVDs are subject to de-lamination problems where the layers of polycarbonate separate, leading to oxidation and read problems. The dye layer, because its organic, can also break down over time, a process hastened by high temperatures and humidity.

While the DVD industry claims DVDs should last from 50 to 100 years, according to the National Institute of Standards and Technology (NIST), DVDs can break down in "several years" in normal environments. Additionally, NIST suggests DVDs should be stored in spaces where relative humidity is between 20% and 50%, and where temperatures do not drop below 68 degrees Fahrenheit.

Gene Ruth, a research director at Gartner, said generally he's not heard of a problem with DVD longevity. And, while he admits that a DVD on a car dashboard could be in trouble, the medium has generally had a good track record.

But Ruth said he can see a market in long-term archiving for a product such as the M-Disc because some industries, such as aircraft engineering, healthcare and financial services, store data for a lifetime and beyond.

Millenniata partnered with Hitachi-LG Data Storage to provide M-Ready technology in most of its DVD and Blu-ray drives. Shumway said the products will begin shipping next month and should be in stores in the beginning of October.

"We felt it was important that we first produce this with a major drive manufacturer, someone that already had models and firmware out there," Shumway said.

Unlike DVDs, which come in 10-, 25-, 50- or 100-disc packs, M-Discs will be available one at a time, or in groups of two or three for just under $3 per disc. Millenniata is also courting system manufacturers in the corporate archive world.

"We're working with some very large channels as we train their distribution networks to launch this," he said. "At the same time, we're launching this at Fry's [Electronics] so consumers can see it and be introduced to this technology."

Mysterious Stone Spheres in Costa Rica Investigated

From: ScienceDaily (Mar. 23, 2010)
— The ancient stone spheres of Costa Rica were made world-famous by the opening sequence of "Raiders of the Lost Ark," when a mockup of one of the mysterious relics nearly crushed Indiana Jones.

So perhaps John Hoopes is the closest thing at the University of Kansas to the movie action hero.

Hoopes, associate professor of anthropology and director of the Global Indigenous Nations Studies Program, recently returned from a trip to Costa Rica where he and colleagues evaluated the stone balls for UNESCO, the United Nations cultural organization that might grant the spheres World Heritage Status.

His report will help determine if sites linked to the massive orbs will be designated for preservation and promotion because of their "outstanding value to humanity."

Hoopes, who researches ancient cultures of Central and South America, is one of the world's foremost experts on the Costa Rican spheres. He explained that although the stone spheres are very old, international interest in them is still growing.

"The earliest reports of the stones come from the late 19th century, but they weren't really reported scientifically until the 1930s -- so they're a relatively recent discovery," Hoopes said. "They remained unknown until the United Fruit Company began clearing land for banana plantations in southern Costa Rica."

According to Hoopes, around 300 balls are known to exist, with the largest weighing 16 tons and measuring eight feet in diameter. Many of these are clustered in Costa Rica's Diquis Delta region. Some remain pristine in the original places of discovery, but many others have been relocated or damaged due to erosion, fires and vandalism.

The KU researcher said that scientists believe the stones were first created around 600 A.D., with most dating to after 1,000 A.D. but before the Spanish conquest.

"We date the spheres by pottery styles and radiocarbon dates associated with archeological deposits found with the stone spheres," Hoopes said. "One of the problems with this methodology is that it tells you the latest use of the sphere but it doesn't tell you when it was made. These objects can be used for centuries and are still sitting where they are after a thousand years. So it's very difficult to say exactly when they were made."

Speculation and pseudoscience have plagued general understanding of the stone spheres. For instance, publications have claimed that the balls are associated with the "lost" continent of Atlantis. Others have asserted that the balls are navigational aids or relics related to Stonehenge or the massive heads on Easter Island.

"Myths are really based on a lot of very rampant speculation about imaginary ancient civilizations or visits from extraterrestrials," Hoopes said.

In reality, archaeological excavations in the 1940s found the stone balls to be linked with pottery and materials typical of pre-Columbian cultures of southern Costa Rica.

"We really don't know why they were made," Hoopes said. "The people who made them didn't leave any written records. We're left to archeological data to try to reconstruct the context. The culture of the people who made them became extinct shortly after the Spanish conquest. So, there are no myths or legends or other stories that are told by the indigenous people of Costa Rica about why they made these spheres."

Hoopes has a created a popular Web page to knock down some of the misconceptions about the spheres. He said the stones' creation, while vague, certainly had nothing to do with lost cities or space ships.

"We think the main technique that was used was pecking and grinding and hammering with stones," said Hoopes. "There are some spheres that have been found that still have the marks of the blows on them from hammer stones. We think that that's how they were formed, by hammering on big rocks and sculpting them into a spherical shape."
