An address from which a disk drive is caused to start reading is set in step SA1, and reading is started in step SA2. Determination is made in step SA3 as to whether an error has occurred. In occurrence of an error, in step SA4, it is determined whether resetting of the read start address in step SA5 has been conducted a predetermined number of times or a predetermined time period has passed from the start of the read operation. If so, the read operation is terminated. If not, in step SA5, the address from which the disk drive is caused to start reading is reset to one sector ahead of the sector currently set. The process then returns to SA2, and the read operation is started from the reset address.
