Provided are a thin film magnetic head having superior overwrite characteristics
as well as having a locally minimized pole width and a method of manufacturing
the same. A top pole chip comprises a first magnetic film that is a top layer portion
of the top pole chip, and a second magnetic film that is a bottom layer portion
of the top pole chip. Both the first and second magnetic films are made of a magnetic
material having a high magnetic flux density of 1.5 tesla or more. Even when the
pole width is locally minimized to about 0.3 m or less, the saturation of
magnetic flux in the top pole chip can be prevented, and therefore superior overwrite
characteristics can be ensured.
