Abstract
PURPOSE: Abrasion resistance and processibility are improved by burying a nonmagnetic substnace in a narrow track head used in VTRs, etc. thereby increasing the thickness of the chip of the head and an S/N is increased by specifying the shape of the buried part thereby eliminating the disturbance of signal from adjoining tracks.
