Abstract
PURPOSE: To make possible the formation of a high precision magnetic gap by burying a Hall element in the concave groove provided in a ferrite substrate.
CONSTITUTION: A concave groove 13 of a specified depth is worked through crystal non-destructive working in the specified position of a ferrite substrate 11 by electrolytic etching or the like and an insulation film 14 of a required thickness is formed through vacuum deposition, etc. Next, the Hall element 15 formed of a protecting film 16 is buried in the groove 13 and an electrode for the element 15 is laminated on part of the film 14 and element 13. Further, fused glass is poured in the gap part 20 formed of the ferrite peice 19 and substrate 11 to form the Hall element head, then the gap of a narrow width determined according to the films 14, 16, etc. and of a length corresponding to the position of the groove 13 is formed with high accuracy. This high precision gap of a narrow width enables the high output head of good S/N to be provided.
