ABSTRACT:
A recording/reproduction device uses a PG signal, generated in a yoke in accordance with rotation of a magnetic disc using a PG yoke, as a timing signal for recording or reproduction of video signals. A noise other than the PG signal is removed therefrom by rejecting a signal unless a signal status of "H" or "L" continues for a predetermined period of time or more. Also, a signal generated with a period shorter than that of the PG signal generated by one full turn of the magnetic disc is masked.
