Magnetic transducer with trim erase and housing therefor

Abstract

A magnetic head assembly and the method of manufacture therefor comprising a generally cylindrical housing having a tapered portion at one end thereof terminating in a circular aperture having an inner diameter, a circular slider body having an outer diameter slightly less than the inner diameter, a media engaging surface and an internal surface and being disposed within the circular aperture and affixed to the housing. The body also includes a first elongated slot disposed along a first diameter and extending through the body, a second slot disposed along a second diameter normal to the first diameter and extending into the body from the internal surface, and a central aperture extending through the body at the intersection of the first and second slots. A read/write transducer has a pair of read/write pole pieces which are separated to provide a read/write gap and which extend into the first slot with the read/write gap positioned with the central aperture. An erase transducer including a pair of erase pole pieces is disposed in the second slot with one-pole piece on each side of the first slot. The ends of the erase pole pieces nearest the read/write pole piece extend into the central aperture and are separated from the read/write pde pieces to form first and second erase gaps.
