Abstract:
An apparatus for reproducing data from a recording medium, the apparatus comprising:a demodulation and error correction unit for demodulating the data output from the recording medium;a decompressing decoder for storing the data directly received from the demodulation and error correction unit into an internal memory provided in the decompressing decoder, decoding the stored data and outputting a memory status signal based on an amount of data stored in the internal memory of the decompressing decoder; anda controller for controlling reproduction of the data from the recording medium based on the memory status signal, wherein the controller includes:a first unit for providing a back track jump signal to a servo control unit based on the memory status signal so that the amount of data stored in the internal memory is maintained within a predetermined range;a second unit for comparing data reproduced at a back-jumped position with data previously stored in the internal memory; anda third unit for controlling decoding of the data stored in the internal memory based on a comparison result by the second unit.
