Abstract
In recording of information, upon reception of a write request from a host computer, recording information from the host computer is stored in a cache memory, and thereafter, a notification of write completion is transferred to the host computer to accept the next request. A request from the host computer is compared with a most recent prior request so as to judge if two requests are sequential write accesses. When it is determined that the two requests are sequential write accesses, a write operation corresponding to the next write access is sequentially performed after a write operation corresponding to the most recent prior request.
