ABSTRACT:
A slider comprises an air bearing surface which is arranged to face a recording medium and a protective film which covers at least a part of the air bearing surface. The protective film includes a first protective film formed on the air bearing surface and made of an amorphous material based on carbon and hydrogen and a second protective film formed to cover the first protective film and made of an amorphous material based on carbon and hydrogen. Further, the atomic fraction of hydrogen in the second protective film is lower than that in the first protective film.
