Abstract

In a rotary head apparatus a first reproducing magnetic head and a second reproducing magnetic head are oppositely arranged between a rotating shaft; and a first recording magnetic head and a second recording magnetic head are also oppositely arranged between the rotating shaft. One of the magnetic head elements of the first recording magnetic head and one of the magnetic head elements a of the second recording magnetic head are connected to a first channel of a rotary transformer; and the other magnetic head element of the first recording magnetic head and the other magnetic head element of the second recording magnetic head are connected to a second channel of the rotary transformer, to thereby enable simultaneous recording and reproducing.
