Abstract: A compact disk reproducing apparatus (26) reads out audio data for a predetermined time T ÄsecÜ from a disk (50) at x times a standard audio data output speed every predetermined time interval T ÄsecÜ and stores the read data in an audio data buffer (60) in response to an audio play request supplied from a computer system. Then the apparatus reads out audio data accumulated in the audio data buffer (60) at a standard audio data output speed to subject the same to audio reproduction processing (61). Since reading out the audio data for the predetermined time T ÄsecÜ finishes in T/x ÄsecÜ, a data reading part is in a stand-by state for the remaining (T - T/x) ÄsecÜ. Thus, when the CD-ROM reproducing apparatus (26) receives a computer data read out request during audio play, it reads out computer data from the disk (50) making use of a latency time (T - T/x) ÄsecÜ not needed during reading out of the audio data.
