<p>PURPOSE:To eliminate the picture recording leakage and also to improve the operability for reservation of broadcast programs, by comparing and operating the picture recordable length of a magnetic tape with the set picture recording time to set the picture recording times in both the standard and long-time picture recording modes. CONSTITUTION:A system control circuit 7 calculates the picture recordable time of a magnetic tape loaded by the signals applied from a magnetic tape discriminating part 1 and reel revolution detectors 2a and 2b after the picture record is started for a reserved program and in case a standard picture recording mode is set by a picture recording mode setting circuit 8. While the set picture recording time of a circuit 3 is compared and operated with the remaining amount of the tape to set a picture recording mode for record of the entire reserved program and also to calculate the recording time. Then a mode switching circuit 4 is controlled based on the data obtained through the arithmetic processing. Thus the revolving speed of a capstan motor 6 is changed.</p> |
