Abstract
An information playback apparatus which can perform random access playback, reverse playback, shuttle playback, etc. quickly and seamlessly. A signal processing unit stores audio data read out from a disc into a buffer memory, and performs information processing for audio playback based on the audio data in the buffer memory. Audio data of certain time durations respectively corresponding to a past and a future with respect to the audio data currently being subjected to audio playback is replenished and stored into the buffer memory. When a jog dial is manipulated, reverse playback, shuttle playback, etc. are performed quickly and seamlessly based on the audio data in the buffer memory. Audio data of certain time durations respectively corresponding to a past and a future with respect to a cue point is also stored into a cue point memory, and when a command to start random access playback is given and/or the jog dial is manipulated, quick random access playback and seamless reverse playback, shuttle playback, etc. are performed based on the audio data in the cue point memory.
