摘要： A periodical signal detection circuit is designed for use in an apparatus which reproduces an information signal and a periodical signal from a recording medium. A separation circuit separates the periodical signal from the reproduced signal. A reference pulse is generated at a repetition frequency which is the same as the frequency of the periodical signal. A first gate circuit responds to the periodical signal obtained from the separation circuit and to the reference pulse signal. A first counter produces an output by counting N of the reference pulses (N is an integer greater than or equal to 2). A second gate circuit passes the signal from the separation circuit according to the output of the first counter. An output circuit detects the signals in responsive to the reference pulse, and the output of either the first or the second gate circuit.

摘要： An apparatus reproduces signals which are recorded on a rotary medium having a main information signal recorded on a spiral main track, with first and second tracking control reference signals which are recorded on sub-tracks positioned between adjacent main tracks. A third tracking control reference signal is recorded on the main or sub-track, on each track turn, during an interval corresponding to the vertical synchronizing signal, within a vertical blanking period of the main information signal. The first and second reference signals are recorded within an interval excluding the interval corresponding to that of the vertical synchronizing signal. A kick pulse is generated for shifting the reproducing element to an adjacent track during a special reproduction mode so that the reproducing element is shifted at an interval other than the interval in which the reproducing element reproduces the vertical synchronizing signal.

摘要： An apparatus for automatically reproducing recorded signals from a rotary recording medium, in accordance with the mode in which signals were recorded. The reproducing apparatus comprises a micro-computer which produces a two-bit mode control signal and a one-bit muting signal. The one-bit muting signal puts one of two processing circuits in a non-operational state, so that the other of the two processing circuits can perform the signal processing in accordance with the mode specified by the two-bit mode control signal. Four codes constituted by the two-bit mode control signal are commonly used to specify four reproducing modes of a video rotary recording medium and four reproducing modes of an audio rotary recording medium.

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.
