Description

ABSTRACT:
A method of manufacturing a thin-film magnetic head, the thin-film magnetic head including a magnetoresistive element, first and second shield layers for shielding the magnetoresistive element, a first shield gap film provided between the magnetoresistive element and the first shield layer, and a second shield gap film provided between the magnetoresistive element and the second shield layer. The method includes the steps of forming the first shield layer, forming the first shield gap film on the first shield layer, forming the magnetoresistive element on the first shield gap film, forming the second shield gap film on the magnetoresistive element, and forming the second shield layer on the second shield gap film. At least one of the first and second shield gap films is formed by stacking a plurality of insulating films formed by chemical vapor deposition.
