IPC: G06F12/08
Filed: 1988-12-23
Abstract: PURPOSE:To decrease the access frequency to an optical disk medium for improvement of the processing speed and at the same time to increase the lifetime of the optical disk medium by using a part of a main memory as a cache memory and at the same time carrying out the pre-reading control. CONSTITUTION:At least an optical disk control data area and an image data area are prepared to a cache memory using partly a main memory 2a in response to the area of an optical disk device 5. While the areas 1 and 2 are added to the memory 2a to set the data read out of the device 5. Thus the pre-reading control is possible. As a result, the next page data can be read out of the device 5 during the expansion of the first page data when the pages are turned over. Thus the page turn-over speed is increased. In other works, the image data and the optical disk control data can be pre-read with high efficiency. Then the access frequency is decreased to the device 5 together with improvement of the processing speed and at the same time the lifetime of the device 5 can be increased.
