RECORDING MEDIUM, RECORDING METHOD, AND RECORDING DEVICE

摘要

PROBLEM TO BE SOLVED: To simply and easily realize post-recording by periodically arraying a recording block for video data and audio data on recording tracks at a predetermined ratio. SOLUTION: One logical zone consists of data areas and spare areas. A minimum recording unit in one logical zone is an ECC block, and each ECC block is distributed for video recording and audio recording at a predetermined ratio. Namely, each 21st ECC block from a head of the data area is allocated for audio recording, and the other ECC blocks are allocated for video recording. When post-recording a video data or an audio data onto such a disk, the video data or the audio data are recorded in an ECC block for the video data recording in the neighborhood of the reproducing position at the time of post-recording or in the recording block for the audio data.
