ABSTRACT:
In a method for producing a magnetic head slider 20, wherein, after a sacrificial layer 31 is formed on a substrate 30, a protective film layer 21, an adhesion layer 22, a head element layer 23 and an air bearing surface layer 28 are sequentially formed thereon, and finally a slider body 29 is formed by a plating, and then the magnetic head slider 20 is separated from the substrate 30 by the removal of the sacrificial layer 31. In order to prevent the air bearing surface layer from breaking or cracking due to the generation of bubbles during a process for removing the sacrificial layer by etching or the like and separating a magnetic head slider from a substrate, after the head element layer 23 has been formed but before the air bearing surface layer 28 is formed, a first hard film layer 24 consisting of a hard material is formed.
