摘要： An automatic tracking control system for use in a magnetic recording and/or reproducing apparatus, which system includes a servo control circuit for controlling a tracking phase of a rotary head assembly; a search control circuit for causing the servo control circuit to vary the tracking phase in a predetermined quantity thereby to make a search so as to reciprocate within a predetermined tracking phase area; a detecting circuit for detecting envelope voltage values of an audio signal and a video signal reproduced for each search point and summing such signals together to provide a composite envelope value; and a reference tracking phase setting circuit for detecting the tracking phase, at which an optimum tracking can be attained when the reproduced signals are integrated from the composite envelope value, thereby to set a reference tracking phase which provides a reference value to the servo control circuit.

摘要： A one-piece type video camera comprises a device for taking the image of a subject, a device for collecting the voice and a device for magnetically recording the image and voice, all of which are built in the camera as one piece. The voice collecting device includes a microphone for collecting the voice incoming from the subject and another microphone for collecting the operator's voice. The operator's voice is subtracted from the voice incoming from the subject such that only the latter will be recorded. The operator's voice is utilized in the voice recognition technique so as to control the entire system of the video camera. In a preferred embodiment, the microphones are directional microphones.

摘要： In a magnetic recording and reproducing apparatus, audio signals are recorded over a track where video signals have been recorded. The audio signals are subject to time base compression, and are recorded on a magnetic recording medium. The audio signals undergo time base expansion before they are reproduced. When recording television signals from a plurality of channels on one magnetic recording medium or reproducing video signals intermittently, the audio signals are recorded without interruption.

摘要： An automatic tracking control system with a servo loop, controlled by a tracking control signal, that adjusts the position of a pickup head in relation to tracks scanned by the head. Adjacent-track crosstalk is extracted by a crosstalk detector and envelope-detected by a crosstalk envelope detector. An automatic tracking control circuit varies the tracking control signal, finds a state that minimizes the crosstalk envelope, and maintains the tracking control signal at or near that state.For double-deck recording systems in which one signal is recorded in surface tracks over another signal, the automatic tracking control circuit seeks a best compromise between minimizing the crosstalk envelope of one of the signals while maximizing the envelope of the other signal.
