Magnetic head with a horizontal slit capable of reading magnetic signals of at high density

Abstract

A magnetic head for use in a VCR includes a pair of cores, a pair of sets of coils, an insulating member, a thin film magnetic layer and a thin film protection layer. Furthermore, a method for the manufacture of the magnetic head includes the steps of: providing a pair of cores having an "I" shaped core and a "C" shaped core; forming an insulating member between posterior portions of the cores, joining the cores with each other; depositing a thin film magnetic layer on a frontal face of each of the cores; patterning the thin film magnetic layer in such a way that the thin film magnetic layer has a horizontal slit; and depositing a thin film protection layer on top of the thin film magnetic layer, thereby forming the magnetic head. Since the magnetic head has the thin film protection layer and the thin film magnetic layer with the horizontal slit which encompasses a magnetic gap and has the width thereof narrower than that of the magnetic gap, it is possible to record magnetic signals on a magnetic tape at high densities or reproduce the magnetic signals thus recorded, and hence it may have a lengthened life span.
