Abstract

PURPOSE: To enable a simple circuit to improve reliability under no external influence, by applying two-channel recording heads with biases which are mutually out of phase.
CONSTITUTION: To respective one-side terminals of recording coils 241 and 251 of recording heads 24 and 25, bias singals are supplied which are outputted by recording bias oscillation circuit 23 and mutually out of phase, and to other-side terminals, right and left recording signals are supplied. Therefore, since a bias strap circuit is never considered to be a load upon the oscillation circuit, the bias strap circuit is unneeded, so that circuit constitution will be simple. Further, recording heads 24 and 25 are symmetrical circuits and bias signals are mutually out of phase, so that definite operation can be obtained without any influence of disturbance, etc.
