摘要： A record/reproduce circuit for VTR comprising two normal reproducing heads with different azimuth angles, a special reproducing head with the same azimuth angle as that of the one normal reproducing head, a rotary transformer through which signals from these heads are supplied to a static circuit section, a change-over means for alternately switching a signal from the special reproducing head and a signal from the other normal reproducing head with a different azimuth angle from that of the special reproducing head, a feedback type preamplifier for amplifying the output of the change-over means, and another feedback-type preamplifier for amplifying a signal from the normal reproducing head with the same azimuth angle as that of the special reproducing head.
