Rotary recording medium reproducing apparatus capable of performing special reproduction |
摘要 |
A rotary recording medium reproducing apparatus for reproducing a rotary recording medium in which an information signal is recorded on a spiral track comprises a reproducing transducer having a reproducing element for reproducing signals from tracks on the rotary recording medium and a kicking mechanism for kicking the reproducing element to an adjacent track when applied with a kick pulse, and a kick pulse producing circuit for producing and supplying a kick pulse to the reproducing transducer according to a reproduction mode which is set. The kick pulse producing circuit comprises a timing signal generation circuit for generating a number of timing pulses equal to a maximum number of kicking positions for one revolution of the rotary recording medium, and judging and producing circuit for producing a kick pulse having a predetermined time width according to a judgement result obtained during a predetermined interval corresponding to a preceeding timing signal, in addition to judging whether a kick pulse is to be produced with respect to a succeeding timing pulse during the predetermined interval corresponding to each timing signal from the timing signal generation circuit.
