摘要 |
<p>A video tape recorder (VTR) records and reproduces a signal distributed to a plurality of channels by use of a memory (3, 6). The VTR comprises one magnetic head (71) mounted on a drum (70), the magnetic head (71) integrally incorporating a pair of magnetic gaps corresponding to different azimuths. The drum (70) is rotated n times as fast as a field frequency, n being a natural number. The time base of the signal distributed to the plurality of channels using the memory (3, 6) is changed in accordance with the rotary speed of the drum (70) and with an angle at which a magnetic tape (18) is wound around the drum (70). <IMAGE></p> |
