ABSTRACT:
A variable speed magnetic medium recording and playback apparatus for reproducing signals prerecorded in defined tracks on a magnetic recording medium by cyclical helical scanning and generating an output video signal subject to noise when more than one track is scanned in a single cycle. The magnetic reproducing apparatus includes a variable speed rotary head for helically scanning the prerecorded signals on the recording medium, a variable speed drive device or a capstan device for moving the recording medium in relation to the rotary head, and a circuit for controlling the speed of the rotary head in correspondence with changes in the speed of the variable speed drive device for reducing noise in the output signal of the apparatus.
