A color video signal recording and reproducing apparatus comprises a first circuit for delaying by a time period T a reproduced time-compressed line-sequential color difference signal in which time-compressed first and second color difference signals are alternately transmitted in time sequence for every time period T, a second circuit for delaying a reproduced luminance signal by a time period 2nT+.alpha., where n=1 or 2 and 0.ltoreq..alpha..ltoreq.T, and a time base expanding circuit supplied with the reproduced time-compressed line-sequential color difference signal and an output signal of the first circuit for writing these signals into a memory responsive to a first clock pulse produced based on a synchronizing signal within the reproduced time-compressed line-sequential color difference signal and for reading out the stored signals responsive to a second clock pulse produced based on a synchronizing signal within an output delayed reproduced luminance signal of the second circuit, so as to simultaneously output in parallel first and second color difference signals having the time base thereof expanded and returned to the original time base and matched with the time base of the reproduced luminance signal.

Color video signal recording and reproducing apparatus

A recording and/or reproducing system for a 4-head type recording and/or reproducing apparatus, comprises a circuit for recording a head discriminating information signal of each of the four heads during the recording, a circuit for reproducing this head discriminating information signal during the reproduction, and a circuit for controlling the rotational phase of the heads so that the recorded tracks on the magnetic tape are reproduced by the same heads which recorded these tracks at the time of the recording. In addition, a magnetic tape having such a discriminating signal recorded thereon, can be played in a conventional 2-head recording and/or reproducing apparatus.
