Perpendicular magnetic recording head
摘要:
A perpendicular magnetic write head capable of suppressing damage and corrosion of a magnetic pole to secure a stable writing performance is provided.A non-magnetic protruding layer protruding from a main magnetic pole layer (tip portion) toward an air bearing surface side is formed on both sides of the tip portion in a writing track width direction. The non-magnetic protruding layer is located closer to a recording medium than the tip portion during writing operation, and more likely to be in contact with the writing medium instead of the tip portion. Since the portion of the protective film covering the tip portion hardly peels off while the portion of the protective film covering the non-magnetic protruding layer is easy to peel off, the tip portion is hardly damaged or corroded. Since the tip portion is protected physically and chemically by the non-magnetic protruding layer, the deterioration of the soft magnetic characteristics of the tip portion is suppressed.
