ABSTRACT:
A video signal magnetic recording and reproducing system having a single rotary head, comprises a time base compression circuit for subjecting a video signal to be recorded to time base compression, to obtain a recording signal in which the time base is compressed in units of a predetermined period, where the recording signal in which the time base is compressed has intervals in which no signal exists between the units of the predetermined period, a recording and reproducing circuit for recording the recording signal in the units of the predetermined period obtained from the time base compression circuit onto a magnetic tape by a magnetic head for each scan, and reproducing the recording signal thus recorded, and a time base expansion circuit for subjecting the signal reproduced by the recording and reproducing circuit to time base expansion, to obtain a continuous reproduced signal.
