ABSTRACT:
A method and apparatus for reproducing data by optically reading out recorded signals from a recording medium. An encoded data decoding unit 4 separates header data from data read out from an optical disc 1. The header data information is sent to a controller 6. The controller calculates the value of the readout data quantity which permits data reproduction, decides the readout patterns of the encoded data and controls data transfer from an encoded data decoding unit 4 to a decoder 5. For special reproduction of variable length encoded data, an optimum readout pattern may be partially selected from the encoded data without causing disorder in the data supply to the decoder.
