Abstract

PURPOSE:To obtain a recorder/reproducer which has a D/A converter of a minimum limit without providing a regulating D/A converter in a special purpose circuit. CONSTITUTION:The recorder/reproducer comprises a regulating D/A converter 1 in which a recording mode and a reproducing mode are commonly used, an exclusive use recording circuit 2 which is operated only at the time of the recording mode, and an exclusive use reproducing circuit which is operated only at the time of the reproducing mode. With this structure, when the recorder/reproducer enters the recording mode, recording mode data is input to the converter 1, a regulating DC voltage output from the converter 1 is input to the circuit 2, and regulated. When it enters the reproducing mode, reproducing mode data is input to the converter 1, a regulating DC voltage output from the converter 1 is input to the circuit 3, and regulated.
