Milpitas, CA (March 19, 2001) – DISC®, Inc. (NASDAQ: DCSR), a leading manufacturer of nearline storage solutions, today announced plans to integrate Sony Corporation’s forthcoming Ultra Density Optical (UDO) format within its enterprise storage libraries, with product availability expected in the second half of 2002.

DISC plans to integrate the new generation drives, currently in development at Sony, into its nearline storage solutions. The initial 40 GB per cartridge capacity for the technology, achieved through the use of violet laser and advanced optics, will be available in both rewriteable and WORM (write once, read many) formats. Customers who currently own or plan to purchase DISC’s 5.25-inch optical libraries can take advantage of the increased storage capacity of the libraries when combined with the new UDO technology.

“Reliability, data availability and cost per megabyte are the driving factors when designing today’s storage systems,” said Bob Riland, VP, Marketing and Sales. “When Sony delivers on the promise of UDO Technology, DISC will be able to deliver nearline storage systems for as little as half a cent per megabyte. The UDO product road map will allow us to continue offering storage devices at a fraction of the cost of RAID.”

Automated storage systems from DISC are known for features such as random access, high data availability rate, quick transfer rates, large capacity and long-term reliability. The advent of UDO technology will allow DISC to continue to provide its current and future customers with leading edge storage solutions in both nearline and data archival environments.
