Abstract
PURPOSE: To lessen the wow and flutter and thus to enhance the sound quality by detecting the fluctuation of the tape speed via the reference signal which is recorded and reproduced via the control track and then controlling the delay time of the aural signal according to the detection of the tape speed fluctuation.
CONSTITUTION: In the recorder/reproducer using magnetic tape 4 which contains at least the control track and the aural track, the reference signal and the aural signal are recorded on the control track and the aural track respectively at the recording time. And at the reproduction time, the tape speed fluctuation component is detected based on the signals reproduced from the control track, and the delay time of the variable delay circuit distributed at the reproduction system line of the aural signal in accordance with the tape speed fluctuation component. In this way, the wow and flutter can be reduced for the reproduced aural signal.
