Abstract:
1. A magnetic head slider testing method that tests characteristics of a magnetic head carried on respective head sliders in a rectangular plate shaped head slider aligned block having many head sliders prior to being cut out into the head sliders comprising the steps of: accommodating many head slider aligned blocks in a tray 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; with a pair of hooks that is arranged above the tray along the one axial direction and is provided with a narrower interval than the width in longitudinal direction of the head slider aligned block and a wider interval than the width of the step portion, hanging up one of the head slider aligned blocks from the tray while hooking both end portions in the longitudinal direction thereof; transferring the hanged up head slider aligned block above a step portion provided at the top end side of a table, having a narrower width than the interval of the pair of hooks and stepping down in a direction perpendicular to the width direction thereof, lowering the pair of hooks to the step portion while acrossing over the step portion in the width direction thereof and mounting the head slider aligned block on the step portion; positioning the head slider aligned block mounted on the step portion in two axial directions among XYZ directions by interposing between the pair of hooks and the step portion and by butting 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 further positioning the head slider aligned block in the remaining one axial direction 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.
