ABSTRACT:
A method, apparatus and computer program for causing a host computer to optimize execution of plural requests for access to plural data storage locations on a rotating disk, included in a disk storage device, based on a rotational position of the disk relative to a position of a read/write head. The host computer stores position information representing a rotational position of the disk, detects whether plural requests are to be executed, and when plural requests are to be executed, optimizes execution of the requests by reordering a sequence of execution of the requests in a manner to reduce a total service time of the requests based on the position information.
