ABSTRACT:
An apparatus and a signal processing circuit for reproducing data stored on a disc to prevent a buffer memory from experiencing overflow/underflow, and/or to reduce power consumption in a digital-to-analog converter. When the data to be read is ROM data, reading from the buffer memory is conducted in response to a varying frame clock signal, and the frequency of a reference clock signal to the digital-to-analog converter is reduced.
