Abstract
A multiple disk drive array storage device is described which emulates the operation of a single disk drive so that the handshaking and protocol between the array storage device and the host computer appears to the host computer to be that of a single disk drive. The array storage device includes a plurality of individual disk drives, each of which having its spindle synchronized to the other disk drives using a master clock synchronization. Digital data words are received by the array storage device controller which divides the words into subparts and writes each subpart to a different disk drive within the storage device. The buffering and formatting of the digital data for reading and writing from the individual disk drives is accomplished by the controller transparent to the host computer.
