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 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 is provided, and   wherein the pressing mechanism includes an elastic body composed of a plate spring that contacts the movable support part and elastically presses the movable support part.   
   
   
       2 . A slider tester according to  claim 1 , wherein the elastic body is provided so as to be capable of applying a load that matches a float rigidity of the slider to the slider. 
   
   
       3 . A slider tester according to  claim 2 , wherein the elastic body is set in a state where the plate spring is preloaded so that a load that matches the float rigidity of the slider is applied to the slider when the movable support part contacts the plate spring. 
   
   
       4 . A slider tester according to  claim 3 , wherein the elastic body has dimensional tolerances so that the plate spring can be adjusted to a predetermined preload value. 
   
   
       5 . A slider tester according to  claim 1 , wherein a pressing-in margin for causing the slider to float stably is set for the elastic body. 
   
   
       6 . A slider tester according to  claim 1 , wherein the elastic body is provided by folding a plate spring in a Z shape and the movable support part contacts a movable end of the plate spring. 
   
   
       7 . A slider tester according to  claim 1 , wherein the elastic body is provided by cantilevering a plate spring formed as a flat plate and the movable support part contacts a movable end of the plate spring. 
   
   
       8 . A slider tester according to  claim 1 , wherein the elastic body is provided by holding a plate spring shaped as a flat plate at both ends and having the movable support part contact an intermediate part of the plate spring. 
   
   
       9 . A slider tester according to  claim 1 , wherein the elastic body is provided by a plate spring that is oval-shaped when viewed from the front and is provided so that the movable support part contacts a flat part of the plate spring. 
   
   
       10 . A slider tester according to  claim 1 , wherein the elastic body is provided by a plate spring bent into a wave shape and is provided so that the movable support part contacts a movable end of the plate spring.
