Patent ID: 7987583

Claim:
A magnetic head slider testing apparatus that tests characteristics of a magnetic head carried on respective head sliders in a rectangular plate shaped head slider aligned block where many head sliders are aligned prior to being cut out into the head sliders comprising: a tray that accommodates many head slider aligned blocks while arranging the longitudinal direction of the head slider aligned blocks along one axial direction among XYZ axial directions and aligning and supporting the head slider aligned blocks with a predetermined interval along another axial direction among the XYZ axial directions; a table includes a step portion having a width shorter than a length of the head slider aligned block in its longitudinal direction and stepping down at the top end side of the table to the direction perpendicular to a width direction of the table on which one of the head slider aligned blocks is mounted; a pair of hooks that is arranged above the tray along the one axial direction and has a narrower interval than the length of the longitudinal direction of the head slider aligned block and a wider interval than the width of the step portion; and a transfer mechanism that hangs up one of the head slider aligned blocks from the tray with the pair of hooks while hooking both end portions in the longitudinal direction thereof, transfers the head slider aligned block that is hung up above the step portion, lowers the pair of hooks to the step portion in a state of crossing over the step portion in the width direction thereof and mounts the head slider aligned block on the step portion, wherein the head slider aligned block mounted on the step portion is positioned in two axial directions among XYZ directions by being interposed between the pair of hooks and the step portion and by being butted of a bottom face and a side face of the head slider aligned block with a bottom face and a side face of the step portion, and the positioning of the head slider aligned block in the remaining one axial direction among XYZ is performed by moving the table in the remaining one axial direction along the longitudinal direction of the head slider aligned block mounted on the step portion.
