A compressed data recording and/or reproducing apparatus has a compressed data reproducing system for at least reproducing digital data from one recording medium such as a magneto-optical disc in which digital data is bit-compressed and recorded and a compressed data recording system for at least recording digital data in one other recording medium such as an IC card in which digital data is bit-compressed and recorded. The compressed data recorded in the one recording medium of the reproducing system is reproduced and transmitted to the recording system. The compressed data is also bit-compressed at the same or a lower bit rate and recorded in the other recording medium. For this recording, a processing block of the bit compression is selectively deleted in accordance with a scale factor of the bit, compression.
