Abstract
A rotary head assembly for use in a helical-scan magnetic recorder-reproducer includes a pair of magnetic head tips of single-crystal ferrite mounted on an axial end of a rotatable cylinder in substantially diametrically opposite relation to each other, each of the magnetic head tips having two tip members joined to each other through a mating interface and a surface for sliding contact with a magnetic tape. A body of a rigid adhesive is applied to an end of the mating interface remote from the surface. The rigid adhesive is highly rigid and substantially nonelastic for suppressing vibration. The rigid adhesive body attached to the magnetic head tip suppresses vibration of the magnetic head tip to reduce noise produced by the sliding contact between the magnetic head tip and the magnetic tape. The rigid adhesive body increases the rigidty of the magnetic head tip.
