摘要： A helical scanning video tape recorder for recording and reproducing video signals and audio signals to/from a magnetic tape. The video tape recorder includes an analog signal reproducing mode in which an FM luminance signal and a down-converted chrominance signal are reproduced from the magnetic tape by a pair of magnetic heads having a first azimuth angle and an FM audio signal is reproduced from a deep layer of the magnetic tape by a pair of magnetic heads having a second azimuth angle, and a digital signal reproducing mode in which a digital signal is reproduced from the magnetic tape by the pair of magnetic heads having the second azimuth angle. The digital signal is converted into a signal having a frequency in a frequency band higher than a frequency of the FM audio is signal. The video type recorder also includes a recording mode detector and a controller.

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.
