ABSTRACT:
A magnetic recording apparatus of the rotary head type has a cross-talk cancelling function. A plurality of rotary magnetic heads are used to record signals on a magnetic recording medium and a correction signal is formed by using a record signal which is being fed to any one rotary magnetic heads among the rotary magnetic heads to which the record signal is fed during a period, when the record signal is being fed through different rotary transformers, to at least two rotary magnetic heads among the plurality of rotary magnetic heads, and the correction signal thus formed is used to correct the record signal fed to the other rotary magnetic head. As a result, the cross-talk component which may be produced in the record signal between the rotary transformers located at different positions can be effectively removed.
