ABSTRACT:
A video signal reproducing apparatus for reproducing video signals from a record bearing medium on which many recording tracks are formed in parallel to each other with a given-period portion of the video signal recorded in each of the tracks are arranged: To compare, on the basis of signals reproduced by a reproducing head, the level of a reference signal with that of a reproduced state detection signal the level of which varies according to the reproduced state of the video signal; to determine, on the basis of the result of comparison, whether or not the video signal reproduced by the reproducing head is to be written into a memory device which is capable of storing the given-period portion of the video signal therein; and to change a level relation between the reproduced state detection signal and the reference signal from one level relation over to another according to the track pitch of the recording tracks which is detected using the signals reproduced by the reproducing head.
