Abstract
A slider body of a magnetic head slider has a leading end located upstream of an air flow generated between the slider body and a magnetic recording medium, a trailing end located downstream of the air flow, and a floating surface opposed to the magnetic recording medium. At least two rails for generating a floating force are provided on the floating surface of the slider body. A magnetic head for reading/writing data is provided at the trailing end of the slider body. A groove formed between the rails is changed in width from the leading end toward the trailing end, thereby generating an attractive force between the floating surface and the magnetic recording medium. Each of the rails has a tapering portion increased in thickness from the leading end toward the trailing end. The tapering portion terminates at a position where each rail is decreased in width from the leading end toward the trailing end. This magnetic head slider is improved in that its floating characteristics are less influenced by working variations of the tapering portion.
