ABSTRACT:
Each track on a recording medium has a video area used for recording video and audio data, and an audio area used exclusively for recording audio data. The audio area has two regions used for recording odd-numbered audio data segments and even-numbered audio data segments, respectively. The data recorded in one of the two regions may be interleaved to further reduce vulnerability of the audio data to errors. Parity data for the audio data is recorded in a third region located between the first and second regions in each track. The audio data represents a left and a right channel. The left channel audio data is recorded in a first set of consecutive tracks, and the right channel audio data is recorded in a second set of consecutive tracks.
