ABSTRACT:
A magnetic head for recording and reading out of a magnetic recording medium in a perpendicular magnetic recording system is described in which the surface which is close to or in contact with the recording medium are covered with a film of a glasslike carbon material. This film improves the lubrication properties with respect to the adjacent recording medium and serves to prevent abrasion.
