Abstract
A thin-film magnetic head includes a substrate with a surface, first and second shield layers formed above the substrate, and a MR sensor element formed between the first and second shield layers. The MR sensor element has a magnetic sensing region formed with a specific slant angle against the surface of the substrate.
Claims9
A thin-film magnetic head with an air bearing surface opposed to a magnetic recording medium in operation, comprising:
- a substrate with a surface;
- first and second shield layers formed above said substrate;
- and
- a magnetoresistive effect sensor element formed between said first and second shield layers, said magnetoresistive effect sensor element having a magnetic sensing region with only one inclined surface at a specific slant angle in said air bearing surface toward the surface of said substrate.
