Positioning device for magnetic head and disk tester with rotating tool support

摘要

A positioning device for magnetic head and disk tester comprises a base plate (100) which supports a rotary spindle (170), for rotating a magnetic disk (168) with a medium to be tested or to be used for testing, and a rotary platform (150) which may slide in one direction (A) along guide shafts (106 and 108) attached to the base plate (100). The rotary platform rotatingly supports a tool support (208) which supports a mechanical arm (218). The latter supports a pair of head holders (220 and 222) with respective read-write heads (228 and 222) to be tested or to be used for testing the disk. The positioning device of this type makes it possible to replace the heads in a convenient position unobstructed by other parts. This is achieved by unlocking the tool support (208) from the rotatable platform (150) by pushing down a lock finger (234) and turning the tool support with the head away from the working position.
