摘要:
An address signal reproducing system is provided in a rotary recording medium reproducing apparatus which reproduces signals from a rotary recording medium by a reproducing element, where the rotary recording medium is recorded with an address signal in units of predetermined sections for a plurality of sections for each track turn of the rotary recording medium. The address signal reproducing system comprises a kick pulse signal generator for generating a kick pulse signal for forcibly shifting the reproducing element to an adjacent track, a shifting circuit for performing tracking control with respect to the reproducing element and shifting the reproducing element to an adjacent track when applied with the kick pulse signal generated by the kick pulse signal generator, and a stopping circuit for stopping the kick pulse signal from being generated by the kick pulse signal generator during an interval in which the reproducing element traces over at least one of the predetermined sections of the rotary recording medium. The reproducing element reproduces the address signal under a tracking controlled state without being shifted, during the interval in which the generation of the kick pulse signal is stopped by the stopping circuit.
