A disc player is proposed for playing discs with optically stored data on which information is digitally stored in tracks. The disc player has a read/write memory for buffering data blocks that are read into the read/write memory at a first clock rate and are read out of the read/write memory at a second clock rate. To fill the read/write memory, the first clock rate is selected to be greater than the second. The data stored in the read/write memory can be read out throughout the duration of a track jump. Moreover, an operating mode is provided in which excerpts of music pieces stored on a compact disc are played in sequence. At the first clock rate, a sufficiently large quantity of data can be stored in the read/write memory to ensure that the data can be reproduced at the second clock rate throughout the entire duration of the jump times. The track jumps can be controlled by a control unit in such a way that, depending on how the data is evaluated by the evaluation unit, jump commands are delivered to a servo unit which cause the scanning optics to make appropriate track jumps to maintain a specified volume, a specified rhythm, a specified audio frequency, etc. |
