ABSTRACT:
Disclosed is a ramp used for the controlled loading of a head of a head stack assembly (HSA) onto a disk of a disk drive. The HSA includes an actuator arm, a head, and a loading surface. The ramp comprises a base structure and at least one ramp finger projecting approximately perpendicularly from the base structure. In order to load the head in a controlled manner onto the disk, the loading surface of the HSA is rotated along the ramp finger until the head is in a load position. The base structure is then actuated in a vertical direction such that the ramp finger is correspondingly actuated in the vertical direction towards the disk until the head is loaded onto the disk.
