Title: Magnetic recording and reproducing device
Inventor: TSUJI SHIGEKI
IPC: G11B5/027
Filed: 1989-07-27
Abstract: PURPOSE:To reduce random noise at the time of reproducing which occupies the greater part of brightness noise without producing an adverse effect on a reproduced brightness signal by reproducing an identical track with the aid of using N heads, providing a reproduced signal processing circuit to the respective heads, making the time bases of the reproduced signals coincide with the aid of a delay circuit and arithmetically calculating the respective reproduced signals at the same time. CONSTITUTION:The brightness signal output Ya of a chrominance signal separation circuit for a brightness signal 6b is delayed by the delay circuit 7 and the timing thereof is adjusted to the brightness signal output Yb of the separation circuit 6b. Besides, the time bases of the brightness signal outputs Ya and Yb are corrected by time base correction circuits 8a and 8b which synchronously execute read-out and added by an adder 9. Therefore, the voltage of the reproduced brightness signal becomes double. However, since the random noise generated at the time of the reproducing becomes no more than square root times, the S/N of the brightness signal is improved by about 3dB. Thus, the S/N of a video signal is improved without damaging the information of the video signal.
