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： A reproducing apparatus is capable of performing special reproduction of information signals recorded on a rotary recording medium. The information signals are recorded in either spiral track turns or concentric tracks. The reproducing apparatus comprises a detector for generating a rotation detection signal having a frequency which varies proportionally to the rotational speed of the rotary recording medium. A special signal generator generates a special reproduction synchronizing signal and a generator generates an external control signal based on a signal which is obtained by variably controlling the frequency of the special reproduction synchronizing signal. A manual switch varies the frequency of the special reproduction synchronizing signal by controlling the control signal generator responsive to an output code signal corresponding to a position of the manual switch. The manual switch is positioned at a predetermined neutral position to produce the external control signal once every one rotation of the rotary recording medium, to repetitively reproduce the same track. The manual switch varies the frequency of the external control signal to vary, with predetermined steps, a speed of picture motion of the reproduced information signal, corresponding to positions of the manual switch.

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.
