The best of tapes and disks

Article Abstract:

Laser-based tape systems combine tape- and optical-storage technologies. The result is a high-capacity technique that stores data at a cost of only a penny per megabyte. It means that optical tape costs half as much as magnetic tape and only a fifth as much as compact disks. And because optical tape systems 'read' and 'write' using beams of light, optical tape is not likely to be damaged by repeated use. Creo Products Inc, Burnaby, British Columbia, is the only company that actually markets an optical tape system, but Lasertape Systems, Inc, Campbell, CA, is developing an inexpensive optical product, to be introduced in 1992. Lasertape's system, which will cost $25,000, will be compatible with 3480 magnetic tape cartridges, which work with IBM computers.

Different strokes for computing

Article Abstract:

A variety of new keyboards have been developed in response to the need for more comfortable and ergonomic computer equipment. A steady rise of computer-related injuries, due to prolonged repetitive typing, has led to mounting insurance claims and lawsuits against equipment manufacturers and companies. Businesses are finally recognizing the need for better keyboards. Several new keyboards such as Anthony Hodges' Tony! retain the QWERTY keyboard configuration, but incorporate hinges for a more flexible keyboard. Industrial Innovations of Scottsdale, AZ, has developed Datahand keyboard, which rejects traditional keyboard design for a more radical finger-oriented feel. The Datahand costs $3,000, but could cost as little as $300 if mass produced.
