发明名称 Tracking control arrangement in a magnetic recording and reproducing device.
摘要 <p>A tracking control arrangement for a video tape recorder effects simultaneous recording and then simultaneous reproduction of four channel recording tracks (TRa, TRb, TRc, TRd) formed on a magnetic tape (2) under tracking control effected by detecting tracking error in dependence on the phase difference between reproduced signals from two adjacent recording tracks (TRc, TRd) of the four at the time of reproduction, the adjacent two recording tracks (TRc, TRd) being recorded with different azimuth angles. A signal delayed by a delay circuit (100) with respect to the signal recorded in one (TRd) of the two adjacent recording tracks is recorded in the other one (TRc) of the two adjacent recording tracks, thereby permitting tracking control by bimorph plate (3A, 3B) or capstan servo control (106) in dependence on the phase difference between the reproduced signals produced from two magnetic heads (1C, 1D) corresponding to the two adjacent recording tracks (TRc, TRd). </p>
