    摘要： A tape run control unit in the magnetic recording/reproducing apparatus is provided with a discrimination element and a control element. The discrimination element detects a stand-by time until a signal to be recorded is received in repositioning of the tape and generates a discrimination signal for discriminating the length of the stand-by time. The control element controls tape run driving unit such as a capstan motor during the reposition and controls the stop position of the tape such that a magnetic head scans the portion of the tape where no data is recorded. After completion of repositioning, furthermore, the control element works according to a discrimination signal so as to select the stop mode which involves the release of pinch roller when the stand-by time is long and to select the mode for simply stopping only the capstan when the stand-by time is short.

    摘要： A tape loading mechanism for a video cassette recording apparatus in which a magnetic tape held in the cassette is withdrawn therefrom by a tape loading arm and is wound around a rotary cylinder. During this time, the cassette is fixed on the upper surface of a chassis having a cam bore, which is driven by a rotary arm in which a pin inserted in the cam bore is set up. This cam bore is provided with a first cam surface having a radius of curvature equal to that of a locus of a turning movement of the pin, a second cam surface formed continuously from the first cam surface and having a radius of curvature different from that of a locus of a turning movement of the pin, and a third cam surface formed continuously from the second cam surface and having a radius of curvature equal to that of a locus of a turning movement of the pin. Accordingly, the movement of the cassette is started at a predetermined period of time after the movement of the tape loading arm has been started, and it is completed before the movement of the tape loading arm has been completed.
