ABSTRACT:
A rotary recording medium reproducing apparatus for reproducing a rotary recording medium in which a plurality of fields of video signals are recorded for each track turn on a spiral track comprises a reproducing transducer having a reproducing element for scanning over tracks on the rotary recording medium to reproduce recorded signals, and shifting device responsive to a signal applied thereto for shifting the reproducing element towards the outer side or the inner side on the rotary recording medium, and a circuit for producing shifting a signal in order to shift the reproducing element by one track pitch towards the outer side on the rotary recording medium every time the reproducing element reaches one predetermined position on the rotary recording medium, and capable of producing a shifting signal for shifting the reproducing element towards the outer side or the inner side on the rotary recording medium according to the slow-motion ratio and the direction of the slow-motion reproduction when the reproducing element reaches another predetermined position on the rotary recording medium. The shifting signal is supplied to the shifting device. The tracks are reproduced a plurality of times with respect to each track turn, to perform a slow-motion reproduction.
