ABSTRACT:
A rotary magnetic head drum arrangement comprises a lower fixed drum with an upper rotatable drum mounted thereon. A head base member is mounted in a base portion of the upper rotatable drum such that a flexible head mounting portion of the head base member is positioned across a fulcrum. A pairing adjustment screw is provided at a predetermined adjustment point for exerting pressure on the head mounting portion at a point thereon remote from the fulcrum for changing a position of a magnetic head secured on the head mounting portion. A distance between the fulcrum and the adjustment point is made to be longer than a distance between the fulcrum and the head on the head mounting portion.
