  • Multipoint bending apparatus for lapping heads of a data storage device
    Patent number: 6475064
    Abstract: An actuator adapted to adjust the profile of a carrier supporting a bar relative to a lapping surface. The carrier including a plurality of spaced control or actuation points along the length of the carrier for adjusting the profile of the mounting surface of the carrier adapted to support a bar for lapping. The actuator adapted to actuate the carrier at the spaced actuation points and including a plurality of actuation members movably actuated via pressure supplied to the actuation members. The actuation members are supported in spaced staggered relation in chambers in a manifold for bidirectional actuation. The actuation members are spaced relative to the spaced actuation points and are supported relative to the manifold to provide precision actuation for incrementally adjusting the profile of the carrier.
