ABSTRACT:
A reproducing apparatus for reproducing blocks from a recording medium on which a plurality of signal blocks are recorded on plural recording tracks, uses a rotary head which is rotated at a speed equal to at least twice the normal speed. Error detection of a reproduced signal is performed for each signal block, and a detection signal and a reproduced signal of the corresponding signal block are written into a memory. If the detection signal indicates that no error is detected, the reproduced signal from the corresponding signal block is prevented from being written again into the memory. A reproduced track address signal and a reference track address signal are compared, and in accordance with the comparison result, translation of the recording medium is controlled.
