Description
The Electrical Communication Laboratories (ECL) of Nippon Telegraph and Telephone Public Corporation (now NTT) aimed to improve the performance and economy of file memory, which accounted for a large share of system cost, and in 1984 started development to increase the capacity and speed of magnetic disk units while developing the DIPS-11/5E Series. In 1986, they achieved practical application of a high-capacity, high-speed magnetic disk unit (commonly referred to as GEMMY: Giga-byte capacity magnetic memory).
