<p>VIDEO SIGNAL RECORDING AND REPRODUCING APPARATUS A video signal recording and reproducing apparatus used with a disc as recording medium comprises a head assembly, disc rotating means for rotating the disc in relation to the head assmbly, a signal path extending from an input terminal to which a video signal is supplied to be recorded to the head assembly, a first control circuit for controlling the disc rotating means so as to cause the disc to have the rotation varying in response to the phase of a synchronous signal, such as a horizontal synchronous signal in the video signal supplied to the input terminal, variable delay means provided in the signal path for delay the video signal supplied to the input terminal to vary the time base thereof, and a second control circuit for controlling the delay time in the variable delay means so as to cause the video signal derived from the variable delay means to have the time base varying in response to the phase of a reference signal, such as a horizontal reference signal reproduced from the disc through the head assembly.</p> |
