Slider tester

Abstract

A slider tester includes a driving unit that rotates a test medium, a set plate that detachably supports a slider as a single body, and an investigating apparatus that is electrically connected to the slider supported by the set plate and investigates the characteristics of the slider. A movable support part 30 that tiltably supports the slider is provided on the set plate. There is also provided a pressing mechanism that elastically presses the slider via the movable support part toward a surface of the medium to dispose the slider floating over the surface of the medium. The pressing mechanism includes an elastic body 56 composed of a plate spring that contacts the movable support part and elastically presses the movable support part.

1 . A slider tester comprising a driving unit that rotates a test medium, a set plate that detachably supports a slider as a single body, and an investigating apparatus that is electrically connected to the slider supported by the set plate and investigates the characteristics of the slider,
 wherein a movable support part that tiltably supports the slider is provided on the set plate, and a pressing mechanism including a pressing pin that contacts the movable support part and elastic means that elastically presses the slider via the pressing pin toward a surface of the medium to dispose the slider floating over the surface of the medium is provided, and   wherein an ultrasonic generator that reduces the sliding resistance of the pressing pin is attached to the pressing mechanism.
