发明名称 Video signal recording and reproducing apparatus
摘要 A video signal recording and reproducing apparatus used with a disc as recording medium comprises a head assembly, a disc rotating drive for rotating the disc in relation to the head assembly, 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 drive so as to vary the disc rotation in response to the phase of a synchronous signal, such as a horizontal synchronous signal in the video signal supplied to the input terminal, a variable delay provided in the signal path for delaying 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 so as to vary the time base of the video signal derived from the variable delay in response to the phase of a reference signal, such as a horizontal reference signal reproduced from the disc through the head assembly.
