Abstract

PURPOSE: To manufacture a multi-element magnetic head with a little dispersion in recording track width by etching each magnetic substance part while magnetic-substance layer edges at a magnetic gap side are continuously coupled and then by removing continuously-coupled parts by cutting.
CONSTITUTION: On insulating layer (magnetic gap layer) 2 formed covering partially several coils 1 on a magnetic substance substrate, a magnetic substance layer is formed which consists of continuous common part 6 and peninsular part 7 projecting from it, and on it, resist pattern 5 is so provided that a desired magnetic core can be formed. Next, the magnetic substance layer is etched in a nitric acid-based etching solution and after resist pattern 5 is removed, a protective layer is provided at a required part of magnetic substance layer 6 and a protective substrate is further bonded, thereby giving a head mechanical strength. Next, common magnetic substance part 6 is removed by cutting as shown by dotted line 8 and a multi-element magnetic recording medium with this part used as a recording surface can be obtained.
