摘要:PROBLEM TO BE SOLVED: To shorten the access time by setting a status compression number suitable for the number of transfer sectors from an optical disk to a host as an optical disk drive. SOLUTION: A status generating part 210 generates a status representing an internal state of an optical disk controller 200 for each sector of a disk 100. A status compressing part 220 compresses the status with a suitable compression number in accordance with a reading area and the number of transfer sectors designated by the host 2 and transfers the compressed status to a system controller 300.
