ABSTRACT:
A tool that loads magnetic heads onto the disk of a hard disk drive. The tool has a first arm which has an alignment block and a plurality of fingers. The first arm cooperates with a second arm which has an alignment slot and a plurality of second fingers. The arms are coupled to an actuator which moves the arms in opposite directions to separate the first fingers from the second fingers. Movement of the arms also causes a first alignment surface of the alignment block to engage a second alignment surface of the alignment slot. The alignment surfaces are essentially parallel with the fingers and insure that the fingers translate relative to each other without any relative rotational movement.
