The actuator includes a housing formed from longitudinal field plates and end plates which are connected together. A cylindrical or rectangular core of ferromagnetic material is mounted inside the housing with its ends connected to the end plates.

A hole is drilled through the core, thereby removing some of the ferromagnetic material of which the core is composed. By placing the hole at the center of the core where the magnetic field due to the permanent magnets is minimal, the field produced by those magnets remains substantially the same.

Abstract: A slider which has a totally reflective surface that can be used by an optical measuring system to measure the air bearing height of a head gimbal assembly ("HGA"). The slider has a rail with a recess area. The rail is coated with a first film that is thin enough to allow a light beam to transmit through the film and reflect from an interface within the slider. The recess contains a second film that does not transmit light so that a directed light beam is totally reflected from the second film. The outer air bearing surface of the first film is separated from the outer surface of the second film by a height H which is measured before the HGA is tested. The HGA is then placed adjacent to a rotating disk to create an air bearing with a height Hp. The outer surface of the second film is separated from the disk by a height Hv. An optical system directs a light beam into the recess to measure the height Hv between the disk and the outer surface of the second film.
