ABSTRACT:
In the magnetic recording characteristics of recording apparatus, when there are three or more magnetic tips disposed on one head base, the extension lines in the depth direction of the head tips pass through the central line of the cylinder. The both outermost head tips on the head base disposed in one window of the cylinder possess head gaps as dummy head, but do not have the function of magnetic recording characteristics of recording, reproducing and erasing. In the disclosed multiple magnetic head, the materials of the head tips on one head base including the dummy head are the same.
