Magnetic head slider including protective film for head-to-medium spacing detecting element
A magnetic head slider includes a magnetic recording part and/or a reproducing part. The magnetic head slider includes a resistance film having temperature dependence of electrical resistance, the resistance film being positioned in the vicinity of an air bearing surface or on the air bearing surface, separately from the magnetic recording part and the reproducing part. The magnetic head slider further includes a first protective film with a smaller milling rate than the resistance film, the first protective film contacting a lower surface of the resistance film in a lamination direction of the magnetic head slider and on the air bearing surface, and/or a second protective film with a smaller milling rate than the resistance film, the second protective film contacting an upper surface of the resistance film in the lamination direction of the magnetic head slider and on the air bearing surface.
