Abstract

PURPOSE: To manufacture easily a narrow-track-width head for VTR by forming a thin nonmagnetic layer on at least either of a couple of blocks of Fe-Al-Si alloys by O2 or N2 ion implantation and then by carrying out the prescribed, work of both the butted blocks.
CONSTITUTION: Into either of blocks 14A and 14B of Fe-Al-Si alloys, e.g. 14A, O2 or N2 ions are implanted to form nonmagnetic layer 20 of 0.2W0.6μ. Next, blocks 14A and 14B, while butted together with a prescribed nonmagnetic gap interposed to form gap part 15, are bonded to form block body 14. Block body 14 is sliced along lines X1, X2... into thin-piece core materials 16 of gap length (Gl). Next, each material 16 is finished by being polished precisely to a prescribed thickness of ≤25μ. Next, material 16, after being fixed to nonmagnetic support (ceramics, etc.) 17, is provided with winding window 18 and then tape slide surface 19 is formed. Thus, a narrow-track head of wear resistance and high precision can easily be obtained.
