Abstract
A thin-film element is formed at an end of a core slider, at which end air exits, and a protective film is formed on the thin-film element. A step-like recess is formed in the protective film near the thin-film element so as to extend longitudinally toward an end at which air exits.
Claims5
A method for manufacturing a magnetic head in which a thin-film element part for writing and/or reading information is formed on an end of a slider that floats over a recording medium, air exiting at said end,
- said method comprising the steps of:
- forming said thin-film element part on a wafer by forming coils, magnetic films, and gaps for writing and/or reading information, the length of the slider corresponding to the thickness of the wafer,
- forming a protective film around said thin-film element part, and
- forming, in said protective film near said gaps, grooves having a predetermined configuration to serve as recesses of said protective film.
The magnetic head manufacturing method as claimed in claim 3, wherein the thin-film element part includes a magnetoresistant element having conductive members connected to the ends thereof.
