Abstract
In a magnetic disk apparatus adapted such that a magnetic disk made of a hard disk type carrier with a magnetic recording region formed on the surface thereof is rotated in a high speed therein, air is introduced between its slider formed integral with a magnetic head and the magnetic disk, whereby the magnetic head is floated over the magnetic disk and allowed to write data on the magnetic recording layer or read data written on the magnetic recording layer, the magnetic disk apparatus is disclosed wherein the angle of obliquity of the main axis of the slider at the innermost circumferential portion of the recording region with respect to the radial direction of the magnetic disk is set to such angle as will bring the floating height of the edge portion of the slider toward the center of the magnetic disk and the floating height of the edge portion thereof toward the outermost circumference are virtually equal to each other.
