Abstract
PURPOSE:To improve the utility ratio of recording capacity by inserting pseudo silent data based on the detection of marking data from a reproduction signal except for the initial prescribed time of the reproduction signal at the time of reproduction. CONSTITUTION:At the time of reproduction, a silent start code '01' and a silent time code TMN are detected from data D1 which have been read from a data memory, and only sound data are sequentially and cyclically written into a buffer memory based on the detection, whereby pseudo silent data are generated at a time corresponding to a value which the silent time code TMN shows. Sound data are sequentially read from the buffer memory and they are supplied to an ADM demodulator. Pseudo silent data are inserted based on the detection of the silent start code '01' halfway, and they are supplied to the ADM demodulator. Thus, the utility ratio of the recording capacity of a recording medium can be improved.
