ABSTRACT:
A video cassette rotary scanner is adapted for high capacity, high speed, digital audio spectrum data recording by the use of a buffer memory and a servo control system. The buffer memory is operative at a speed much higher than that of the tape. The tape is maintained at relaxed tension until a high data occupancy signal from the buffer activates the data write operation. In response, the tape tension is increased for a write operation, and relaxed again only when the buffer sends a low data occupancy signal. The use of the buffer along with capstan, take-up reel and supply reel motors responsive to the two signals permits tape wear to be decreased substantially while increasing tape capacity.
