Abstract

PURPOSE: To shorten the data access time to an optical disk device by using an electronic disk device or a magnetic disk device as a cache to the data access supplied to the optical disk device.
CONSTITUTION: A data access request is issued to an optical disk device 1 from a data requester program 2, and when an optical disk cache processor 3 decides said request as an input request. Thus a control data memory part 4 is retrieved based on a position in the device 1 containing the input request data 11. The data 11 if stored in a cache area part 6 is extracted and sent to the program 2 in the form of the input data 22. In such a way, the following input request data can be sent from the part 6 with no access given to the device 1 as long as the input request data receive accesses successively.
