Joined magnetic head

Abstract

PURPOSE: To reduce sliding noise and to improve workability by forming a titled head of the structure in which polycrystal ferrites and single crystal ferrites are exposed on a tape sliding surface. CONSTITUTION: This magnetic head is made of the structure in which the single crystal ferrites 12, 13 are disposed only on the butt surfaces of the polycrystal ferrites 11, 21 and the polycrystal ferrites and single crystal ferrites are exposed on the tape sliding surface 15. The recording characteristics equiv. to the recording characteristics of the head consisting of the single crystal ferrite alone are thereby obtd. and the sliding noise is suppressed down to the level equiv. to the sliding noise of the head consisting of the polycrystal ferrite alone. In addition, provision of some range to the thickness of the single crystal ferrites is possible and the workability is improved as the single crystal ferrites are disposed only on the contact surfaces of the polycrystal ferrites.
