A magnetic head slider including a plurality of rails adapted to face a magnetic disk. Each of the rails has a longitudinal extension direction substantially in a direction of rotation of the magnetic disk, and a protective film is provided on a floating surface of at least one of the rails. A thickness of the protective film at least in a direction transverse to the longitudinal extension direction of the at least one of the rails is not uniform in the transverse direction.

Magnetic head and magnetic head manufacturing method

A method of manufacturing a magnetic head slider for a magnetic head and the magnetic slider wherein the slider has non-linear rails formed in a floating surface thereof by processing including one of reactive ion etching, sputter etching and an ion milling, and side walls of the non-linear rails are polished after formation of the non-linear rails by the processing.

For removing re-deposited particulates produced during an etching process of a magnetic head slider and forming a minute chamfered portion, a polishing process is carried out by using polishing cloth such as non-woven polyester fabric after having formed rails of non-linear shape on a floating surface by the etching process. Thus, the re-deposited particulates produced during the etching process are removed, whereby the reliability of the floating characteristic of magnetic head is improved.
