Abstract

PURPOSE: To improve a head output by making a groove with no work strain, and also to improve head reproduction efficiency by setting the length of a back-part gap part to nearly zero, by making use of electrolytic etching.
CONSTITUTION: On one main surface 100 of substrate 10 made of a magnetic material, etching resist layer 11 is formed in a belt shape by bonding and its non- bonding part is electrolytically etched to a depth equivalent to operation magnetic gap length (d), thereby forming bonding surface 13 with groove 12 and operation magnetic gap of depth (d). Next, etching resist 14 is formed by bonding so that its pattern will be perpendicular to grrove 12, and track-width control groove 15 is formed by electrolytic etching. Substrate 10 is cut at a position indicated by cahin line 16 and winding groove 17 is provided. This core hald body block 18 is fitted to core half body block 19 and head core block 21 made in one by fusing glass 20 is cut at a position indicated by chain line 22; and tape slide surface 23 is polished and head core 24 is wound with winding 25.
