Title: Magnetic head
Inventor: HIRATA NOBUYUKI
IPC: G11B5/187
Filed: 1991-02-13
Abstract: PURPOSE:To suppress a deterioration of electromagnetic conversion characteristic of a magnetic head by improving wear resistance of a pole. CONSTITUTION:A head element 1 is formed with a material, e.g. alumina, etc., and the pole 2 consisting of a high permeability metallic film is embedded inside thereof. This pole 2 is constituted of a 'Permalloy' alloy 3, carbon protective film 4 and lubricant film 5, then the carbon protective film 4 is formed on the top end of 'Permalloy' alloy 3, and further the lubricant film 5 is applied on the carbon protective film 4. The top end of pole 2 is exposed on a gap surface of the head element 1 and also protruded from the gap surface. Since the carbon protective film 2 and further the lubricant film 5 are thus provided on the top end of pole 2, the pole 2 is not easily worn even if the magnetic head is made to slide on a magnetic disk medium for a long time by adopting a contact recording system, then the deterioration of electromagnetic conversion characteristic of the magnetic head is drastically suppressed.
