Abstract
A quasi contact head comprises a slider with a flying surface opposed to a magnetic disk. A composite layer is formed on the slider at its trailing end so as to contain a head element such as an MR element. The head element is exposed at an exposure surface formed on the composite layer. A step serves to retract the exposure surface from the flying surface. An edge formed between the step and flying surface is subjected to grinding. The edge wears off during the initial rotation of the magnetic disk, so that the flying height of the slider can be set lower.
