Abstract
In order to realize a shape of an air bearing surface of a magnetic head slider which is capable of coping with a lowering of flying height and which has high reliability, at the time of polishing the air bearing surface of the magnetic head slider by bringing the air bearing surface and the surface of a polishing machine into contact with each other, machining is conducted in the condition where the stiffness acting between both the members is enhanced, and the standard deviation of the flatness of the air bearing surface machined and the standard deviation of the recess amount between the air bearing surface and a magnetic element are controlled. Thus, it is possible to efficiently manufacture a magnetic head slider which enables driving at a low flying height.
