Abstract
The present invention is a novel tape drive system in a magnetic recording and reproducing device for recording a video signal intermittently by a rotary magnetic head and recording an audio signal continuously over a wide range of predetermined tape speeds. In a high speed range a conventional brushless DC motor drives the tape. In a low speed range the same motor is driven by additional pulses. The lowest speed in the high speed range is higher than the highest speed in the low speed range.
