A method for fast playback of a disc in a cue or review mode to reproduce therefrom audio data compressed and recorded burstly by a predetermined amount as a unit. The method comprises predetermining a unitary block of data which consists of +E,uns n+EE times (where +E,uns n+EE is a positive integer) the decodable minimum unitary amount of the compressed data; sequentially extracting, out of the informationally continuous data of plural programs on the disc, the data of the unitary block at an interval of +E,uns m+EE unitary blocks (where +E,uns m+EE is a positive integer) in the forward or reverse direction of the continuity of the data; and reproducing the sound from the extracted data. By repeating such playback operation, the audio data of the plural programs can be reproduced in the cue or review mode at a speed higher than the normal playback speed.
