Abstract

PURPOSE: To manufacutre a narrow-track magnetic head for high-density recording and reproduction with high precision, by forming a gap part by oxidizing part of a core by ion implantation after fixing a thin plate of a material of high magnetic permeability to a substrate of a nonmagnetic material.
CONSTITUTION: This describes a magnetic playback head for a tape of high density recording such as a metal tape. Thin plate 14, made of an Fe-Al-Si material of high magnetic permeability to a thickness of ≤30μ, is fixed to substrate 15 of a nonmagnetic material. Next, part of a core is oxidized by ion-implantation to oxidize gap part 16. Next, through winding window 17 is made by ultrasonic-wave work, etc. Next, gap part 16 is worked over the arc to form a tape slide surface. Thus, a high-precision magnetic head of resistance to wear can be obtaied which has a gap length of 0.2W0.8μ and a trck width of ≤25μ.
