ABSTRACT:
Multiple recording and simultaneous regeneration are performed using a storage medium comprising phase pits and a recording layer so that ROM and RAM can be regenerated simultaneously. When data is recorded to RAM while regenerating ROM using the concurrent ROM/RAM recording medium, the start and the end of recording to RAM is controlled using the recording start and recording end signals of the ROM. Therefore the content recording position of the RAM with respect to the content of ROM can be equalized, the delay can be controlled, and the virtual session function and the multiple recording function can be easily implemented at low cost.
