摘要： A method and an apparatus for recording and playing back monitored video data for recording monitored video data generated continuously for a long time on a magnetic tape, with less S/N degradation by shortening the operation time of the VTR to suppress the degradation of the magnetic tape, recording head, and other mechanical items. Video signals from a video camera are converted to digital signals in an A/D converter, compressed and encoded in a compression encoder and decoder circuit, then transferred to a time axis compression circuit which includes a first memory, the second memory, an SCSI controller, and a hard disk unit. The digital signal is thereafter compressed on the time axis and recorded on the magnetic tape loaded in a D-VHS standard VTR via an I/F circuit. Compressing the video data from the compression encoder and decoder circuit on the time axis in the time axis compression circuit makes the recording time of the video data shorter on the magnetic tape than the actual recording time of the video camera. The VTR is only required to record video data intermittently on the magnetic tape and a general home VTR can be adopted as the above VTR, this also prevents the magnetic tape from being damaged.

摘要： In a recording/reproducing apparatus and a reproducing apparatus based on a helical scan system for recording or reproducing a video signal and an audio signal on or from a magnetic tape by use of a magnetic head assembly mounted on a rotary drum, the recording/reproduction of an audio signal in both a standard play mode with a tape speed equal to a standard speed and a long play mode or N-ple play mode with a tape speed N times (N: an integer not smaller than 4) as high as the standard speed is performed by a common audio head. At the time of reproduction in the N-ple play mode, the optimum tracking control is performed by a tracking control system by use of an output of the audio head. At the time of completion of recording in the N-ple play mode, a video signal is supplied with a time prolonged corresponding to the delay of scan of a video head from that of the audio head so that a video track is surely overwritten on an audio track. A high-speed fast feed/rewind speed at the time of N-ple play mode is set to a low value as compared with the tape speed at the time of standard play mode, thereby ensuring the detection of an index signal from the magnetic tape in the N-ple play mode.

摘要： On the occasion of stopping the tape running at a high speed, a winding radius of the tape supply reel is detected to set the tape deceleration rate (a) on the basis of the detected winding radius of the supply reel. After the tape running speed is decelerated up to the allowable speed VL in the predetermined deceleration rate (a), the tape is stopped by effectuating the brake. Thereby, the tape can be driven at the speed higher than the allowable speed VL without generating any damage, enabling reduction of time required for the fast-forward/rewind operation. Moreover, application flexibility is improved by providing a couple of tape running modes at the first high speed V1 which is higher than the allowable speed VL and the second high speed V2 which is lower than the allowable speed VL. In addition, running of the tape can be ceased within the predetermined time t from the input of the stop command signal by specifying the maximum speed Vmax depending on the preset deceleration rate (a) and limiting the tape running speed with the maximum speed Vmax.

摘要： A magnetic recording and reproducing apparatus arranged to use a magnetic tape. The apparatus operates to derive the current taken-up position of the magnetic tape from the signals that are proportional to the rotation frequencies of a capstan motor, a supply reel and a take-up reel. Only when the taken-up position is near the tape end, the apparatus activates LEDs (light emitting elements) for sensing the tape end and photo-transistors (light receiving elements), for sensing the tape end.

摘要： A VTR compatible with the current analog VTR and capable of recording and reproducing digital signals identifies the type of a tape cassette by the presence or absence of a cassette identification hole formed in a digital recording tape cassette determines tape speed for a recording mode on the basis of the ratio between the frequency of a control signal and the rotating speed of a capstan motor, determines the presence or absence of recorded digital signals through the synchronous detection of reproduced output, and decides the mode for recording and reproducing on the basis of those decisions. Thus, the automatic discrimination between the analog mode and the digital mode can be achieved and erroneous operations, such as an erroneous erasing operation can be prevented.
