PALM SPRINGS, CALIF. — A joint development of TeraStor Corp. and Imation Corp. remains on target to release new rewritable, mass-media storage disc technology during the first half of 1998.
James Kwiecien, manager of Imation's optical technology center in Vadnais Heights, Minn., discussed aspects of the project at the ITA International Recording Media Association's Magnetic & Optical Media Seminar, held Oct. 28-29 in Palm Springs.
Kwiecien would not disclose the type of plastics the discs use. But, he noted, ``The cost of plastic substrates is getting cheap.''
The products, based on TeraStor's Near-Field-Recording architecture, will combine the stability of optical technology with the capacity and flying head function of a hard-disk drive, to create a high-performance, high-technology plastic storage disc.
The entries will compete with high-end magneto-optical, 4- and 8-millimeter tape and removable hard-disk products that can store more than 1 gigabyte of data.
TeraStor engineers' patented advancements modify a flying head that includes optical elements as well as a magnetic coil; adapt a solid immersion lens that reduces magnetic bit cell size and increases recording density; and use first-surface recording that places the hardened recording material on the substrate's surface.
First-surface recording ``enables the use of lower-cost [plastic] substrates and the achievement of higher area densities,'' TeraStor said in a news release.
The firm was formed in December 1995 and is located in San Jose, Calif.
Imation has a semiexclusive, long-term license to manufacture products based on the new technology. Imation, an imaging and information company, was spun off from 3M Corp. in July 1996.
