Abstract
A method and an apparatus for performing high-quality read and write operations through a simple operation without being affected by an interruption even when the interruption has occurred in the course of a read/write operation between information storage media. When an interruption occurs in the course of reading program information stored on an optical disc to write the program information onto a hard disk, the write status of the program information which has encountered the interruption and the information for identifying the program information are stored on the hard disk. After the recovery from the interruption, read and write operations are restarted. Then, the program information capable of ensuring the continuity with the program information which has been properly written on the hard disk prior to the interruption is determined in accordance with the write status of the program information which has encountered the interruption and the information for identifying the program information. A read operation is performed from the program information thus determined and then a write operation to write the information on the hard disk.
