PROBLEM TO BE SOLVED: To obtain various reproduced information by reproducing first data and second data of a single piece of optical recording medium in various reproduction modes. SOLUTION: When a system controller 27 discriminates disk identifying data ID from TOC and reproducing mode identification data Im is the first reproducing mode for instructing arithmetic output reproduction in addition, a multiplexer 33 outputs audio data DAEx of 20 bit/sample via a selection circuit 36. When the system controller 27 discriminates disk identification data ID from TOC and reproducing mode identification data Im is the second reproducing mode which instructs the reproduction of an audio signal of the same quality as a general CD, the circuit 36 selects the side of a terminal (a) to output audio data D6U of the 16 bit/sample outputted from a CIRC decoder 29. |
