Abstract

PURPOSE: To improve availability of an optical disk by setting the next memory control information area in an idle area of a data area and at the same time storing the information on the memory control information area in a succession information memory area when a memory control information area is filled.
CONSTITUTION: A central processing unit 11 of a host device 1 sets an index current pointer PCI showing the heat sector of an idle area of an idle area of a data area ADT, and an index work buffer WBI into a work memory 13 for an access to an optical disk. When the area AID is filled and the pointer PCI shown the final index area EID, an area of a prescribed part is set art the next index area AID2 from the head sector of the idle area of an index current area ADT. When no idle area exists any more in an index area, the following index areas are successively set at the idle areas of the data area. Thus the optical disk is used with high efficiency.
