摘要：PURPOSE:To prevent the vertical rocking etc. of a bearing by making the delay times of the first delay circuit and the second delay circuit respectively corresponding to the integral part and the decimal part of a value generated by adding 0.5H to a value generated by subtracting the step difference of an inclined track from the preceding quantity of an auxiliary rotary head. CONSTITUTION:A switch 22 is turned to an up-position during the time when a head A or B tracing a magnetic tape but to a down-position when a head A' is tracing the tape. Accordingly, a brightness signal reproduced by the head A' is delayed by a time longer by a prescribed amount. This amount of delay is made corresponding to the integral part of the value generated by adding 0.5H to the value generated by subtracting the step difference of an linclined track from the sreceding quantity of the head A'. And the delay amount of the delay circuit 9 is made corresponding to the decimal part of said value. As a result, the number of horizontal synchronizing signals between two vertical syncyronizing signals in the reproducing of a still picture by the heads A and A' come to 263 in one field and 264 in the other field, giving a difference of 1.
