Abstract
A high capacity micro-Winchester disk drive is capable of storing approximately 120 megabytes of user data on each storage disk. A digital bus interface connects to data, control and status lines from a host computer, and a cache memory defines a plurality of programmable memory segments for disk data, host data and microcontroller data. The cache memory controller enables read-ahead, write-ahead, and automatic multiple block read and write operations to occur between the disk drive and the host without intervention of the disk drive's embedded microcontroller.
