    摘要: In the present invention, a coil generating DC magnetic field applied to a magnetic head is divided into two in that a first coil and a second coil, which are provided on a frame shape core. An distance of an air gap is shortened, a slider head is held on a table having a top end portion of thin thickness, while advancing and retreating the table in the direction perpendicular to the core, the head slider is inserted into the air gap from the lateral direction. Thereby, the distance of the air gap is reduced to about half of the conventional one and a reduction of inductance of the first coil and the second coil is realized.

    摘要: An inspection method and inspection apparatus of a magnetic disk are provided. A gliding test and a certification test are performed at the same time by simultaneously moving a head for the certification test and a head for the gliding test with a heat distortion utilization mechanism (a micro thermal actuator) along a recording surface of the magnetic disk during rotation at a predetermined revolving speed. A flying height of the head for the gliding test is determined according to a revolving speed of the disk. When the flying height of the head for gliding test is determined according to the revolving speed at the certification test, the head for the gliding test is adjusted to a desired height by adjusting a variation of the heat distortion utilization mechanism disposed on the head for the gliding test. The gliding and certification inspections can be performed at the same time.
