Abstract
PURPOSE: To enable automatic signal and control signal to be surely detected by using a plurality of burst waves of a low frequency of the same frequency for the stop signal and control signal and detecting these with a tracking filter.
CONSTITUTION: In a circuit consisting of a recording medium I, recording part II reproducing part III, the audio signal from terminal AU is recorded in the recording medium I through a high-pass filter 1, after which the burst waves of the automatic stop signal and control signal are supplied from terminal SC and are recorded. At the reproduction, said automatic stop signal and control signal are detected with a tracking filter 15 constituted by a PLL and the central frequency of the tracking filter 15 is made changeable by a time constant changeover circuit 21, whereby the automatic stop signal and control signal may be recorded at the time of both low and high speed reproductions and the system is so constituted that the number of the burst waves thereof is counted with a counter 18, whereby the control signal is obtained.
