Abstract
An apparatus for modifying the playing time of a program including a signal converter (1) for converting a signal (S.sub.1) corresponding to the difference between the time content and the desired playing time of a program to a tape-speed-varying signal (.DELTA.T.sub.D) and a reference-signal-varying signal (.DELTA.T.sub.p). The tape-speed-varying signal controls a delay (5) of a detected capstan signal (T.sub.D). The delayed and nondelayed capstan signal are phase compared (4) to produce a speed control voltage. The tape-speed-varying signal varies the frequency of the capstan reference signal (T.sub.P) in a reference signal generator (2). The capstan reference signal is then phase compared (3) with a signal regenerated from the control track of the tape to produce a phase control voltage. An adder (6) adds the speed and phase control voltages to produce a signal to drive the capstan motor.
