Abstract: To record AV data separately in a plurality of recording media, when a disk end detector detects that the free space in a disk runs out, a stream recording location controller accumulates AV data of a stream buffer in a stream shunt memory. When the disk is replaced with a new one, a disk recordability detector detects whether or not the new disk has become recordable. If recordable, a shunted stream write-back section transfers the AV data held in the stream shunt memory to the new disk.
