Drexler Technology Corp has won far more plaudits and licensees than profits from its LaserCard storage system – used for things like phone cards – so far, but the Mountain View, California company will this week launch a new initiative in the hope of finally hitting paydirt. With its LaserCard Systems Corp subsidiary, it will unveil a prototype of a new off-line, desktop paperless document filing system called LaserCard File, a confidential filing system that will use Drexler’s 3Mb credit-card sized LaserCard optical memory card to store up to 200 document pages permanently. LaserCard File includes an MS-DOS personal computer and graphics terminal for controlling the system and displaying the documents; a LaserCard reader-writer for storing, retrieving and copying data; a facsimile machine for input scanning of documents and hard copy printing of documents; optical memory cards; and appropriate filing and retrieval software. This complete LaserCard File system will be sold through Drexler’s worldwide network of value-added resellers. The system, with 2,000 optical memory cards, is expected to cost about $17,500, and the company says orders placed now will be shipped in late summer.
