Abstract:
A magnetic head for reproducing magnetic recording information, comprising a substrate, a base coat located on said substrate, a magnetic element located on said base coat, and an air-bearing surface formed on a surface of said substrate said surface intersecting a face on which said magnetic element is provided, said base coat having a film thickness ranging from 0.05 &mgr;m to 0.5 &mgr;m, wherein an end face of the magnetic element located on the same surface side as that of the air bearing surface is not projected from an end face of the base coat located on the same surface side as that of the air bearing surface, and is recessed from the air bearing surface by a distance not greater than 1 nm, said air-bearing surface having an averaged surface roughness not greater than 10 nm.
