Control apparatus for simultaneous data transfer
First Claim
1. An apparatus for controlling data transfer between a rotary storage device, having a plurality of heads for different tracks therein, and another storage device, comprising:
- a plurality of transfer circuit means each being coupled so as to operate concurrently with and independently of the other of said transfer circuit means for transferring data therethrough and irrespective of data format of the data to be transferred from the respective corresponding tracks; and
means for simultaneously connecting said plurality of transfer circuit means between said another storage device and said plurality of heads corresponding in number to said plurality of transfer circuit means.

Abstract
An apparatus for controlling data transfer between a rotary storage device such as a magnetic disk having a plurality of heads for different tracks and another storage device such as a disk cache includes a plurality of transfer circuits for the purpose of simultaneous data transfer to and from a plurality of tracks. The transfer circuits operate concurrently with and independently of each other to transfer data therethrough and other than noting the regions to be skipped over, ignoring data format on the track. The apparatus is suitable for preloading a disk cache from a disk.
