Recording medium, recording and/or reproducing apparatus and recording and/or reproducing method.

摘要

A reproducing apparatus of a disc-shaped recording medium (1) has a head (3) a decoder (8), a memory (13), first and second expandor (14) and a controller(11). The disc-shaped recording medium includes a recording area in which only audio data or both of audio data and video data are recorded while intermixed with each other, a first management data area stored with first management data for controlling a recording or reproducing operation of the audio data for the recording area when only the audio data are recorded in or reproduced from the recording area, and a second management data area stored with second management data for controlling a recording or reproducing operation of the audio data for the recording area when both of the audio data and the video data are recorded in or reproduced from the recording area. The head (3) reads out data which are recorded on the disc-shaped recording medium with being compressed. The decoder (8) decodes the data read out by the head. The memory (13) temporarily stores audio data and video data read out from the decoder. The first expandor expands the audio data output from the memory. The second expandor expands the video data output from the memory. The controller (11) controls the reproducing operation of the recording medium by the head on the basis of the first and second management data read out by the head. If it is judged on the basis of the first management data read out by the head that the video data are recorded on the disc-shaped recording medium, on the basis of the second management data the controller controls the head to continuously read out a portion of the recording area of the recording medium in which the video data are recorded, and a portion of the recording area in which the audio data are recorded.
