TeraDisc™ Meets Increased Consumer Demand for High Volume, Low Cost Storage to Protect, Preserve and Distribute Digital Content

Recent Study by Coughlin Associates Indicates Consumer Storage Needs Will Surpass Blu-Ray and HD-DVD Storage Capabilities by 2010

LAS VEGAS, NV--(Marketwire - January 8, 2008) - CES - With consumer consumption of on-demand digital media fueling the exponential creation of digital content and portable devices, a new study published by Coughlin Associates called "Consumer Survey on Digital Storage in Consumer Electronics," indicates that consumer data storage needs will quickly outpace the maximum capacity of current Blu-Ray and HD-DVD storage solutions by 2010. Mempile, a leader in next-generation optical storage technology, is addressing tomorrow's archival storage needs with its proven TeraDisc™ technology capable of currently storing one Terabyte (TB) of data on a single DVD-sized optical disc and with a roadmap of up to 5TB.

The Coughlin study, announced at the Storage Visions conference during CES 2008 (, showed that by 2013 the average household will accumulate a combined total of nearly 9,000 Gigabytes (GB) of commercial and personal data (e.g., movies, music, photos, games, downloads, user-generated content, etc.). The study respondents said that if given the opportunity to own an unlimited amount of inexpensive, permanent, portable storage, 74% would make permanent back-ups of their PC; 66% would put their entire music collection on one disc; 63% would keep personal copies of medical records (including x-rays, charts, prescriptions, etc.); 61% would copy multiple movies to a single disc; and 57% would permanently store entire series of their favorite TV shows.

"Digital media brings a wealth of choice, connectivity and convenience to our lives, but the more we demand of our content, the greater the need for home storage solutions to archive, protect and distribute this content," said Thomas Coughlin, president of Coughlin Associates and chief author of the study. "The typical household in just a few years from now will be vastly different than it is today, in terms of media consumption and distribution as well as the organization and maintenance of growing collections of user-generated content. These large personal media stores will require an integrated organized solution to support PC and laptop back-ups, content from digital video recorders and personal audio and video players, entire movie and music libraries, user-generated content and other personal data."

"The current crop of blue-laser media is being pushed to its limits and will not be able to support the archival storage demands consumers will expect in the very near future," said Dr. Beth Erez, Executive Vice President of Mempile. "The industry needs to focus on developing or embracing new technologies that can scale to meet tomorrow's demand -- such as Mempile's TeraDisc."

Leap-Frogging to Tomorrow's Next-Generation Solutions:

Existing optical media, including Blu-Ray and HD-DVD, record data through light-reflective, semi-transparent layers. However, the capacity of this format is limited to around eight layers of recordable material (approximately 200 GB) because as light passes through these layers it becomes diminished and distorted by the reflections of other layers, making accurate data reading and recording impossible.

Mempile's two-photon technology overcomes this basic limitation by enabling a TeraDisc to remain completely transparent -- both before and after recording. This allows the laser to remain in focus even when reading and writing through previously recorded layers. Thus, a single TeraDisc can record and read 200 virtual layers five microns apart using a red laser, each capable of storing approximately 5 GB of data which may be accessed randomly yielding 1 TB.

Since the TeraDiscs are made from an inexpensive monolithic plastic similar to Plexiglas™, and its drive components are comparable to today's optical drives, the TeraDisc will afford consumers a low cost, high capacity archival storage solution, with plug and play functionality and a data lifetime of more than 50 years.

In early 2007, Mempile held a live technology demonstration for top Japanese electronics manufacturers. More than 100 virtual layers of data were recorded on and read back from a 0.6 mm thick TeraDisc without showing any signal degradation. At ISOM '07, an international conference on optical memory (October 2007, Singapore), the company detailed the opto-mechanical, servo techniques and disc structure of its innovative TeraDisc technology showing its comparability to that of the DVD ecosystem. Towards the end of 2008, the industry can expect to see a demonstration of a prototype of the TeraDisc technology.
