There is disclosed a spinstand for testing a head gimbal assembly. The spinstand includes a gripper operable to grip the head gimbal assembly and a load pick device operable to hold a head gimbal assembly and to move the head gimbal assembly into an exchange position where it can be gripped by the gripper. In the exchange position part of the load pick device registers with the gripper and another part of the load pick device is spaced from the gripper so as to form a space between, in which space at least part of the head gimbal assembly is located in use.

Spinstands for testing a head gimbal assembly

In one arrangement, apparatus for attaching a disk to a spindle of a spinstand has a spindle adapter. The spindle adapter has a drawbar movably disposed within. The drawbar has a connector end that is reversibly connectable to the cap and has a piston that is connectable to a source of fluid pressure. The drawbar is movable in response to fluid pressure so as to urge together the cap and the spindle adapter when connected. The cap and the spindle adapter are capable of holding a disk therebetween. In another arrangement, a movable stage movable over a deck of a spinstand has a lift stage arranged to hold a cap with a disk positioned thereon. The lift stage has at least one actuator for raising the lift stage so that the cap can be connected with a spindle adapter of an inverted spindle of a spinstand.

Apparatus for receiving and positioning a read/write head to a disk in a test apparatus has a deck and a spindle on the deck and on which a disk can be mounted for rotation of the disk. A gripper is provided for holding a head during testing, the gripper being movable over a surface of the deck. A precisor receives a head and accurately aligns the head, the precisor being movable over a surface of the deck. A pick is operable to pick up and place down a head. The precisor is movable to a position where the pick can pick up a head from the precisor and place down a head on the precisor. The gripper is movable to a position where the pick can pick up a head from the gripper and place down a head on the gripper.

Apparatus and method for receiving and positioning a read/write head to a disk in a test apparatus

Apparatus for attaching a disk to a spindle of a spinstand includes a spindle having a fluid pressure port therethrough for delivery of fluid pressure. A spindle adapter is adapted to be attached to the spindle and for holding a disk. The spindle adapter has a piston movable therein to clamp a disk between the piston and an opposing surface in response to fluid pressure applied through the spindle fluid pressure port. A disk can be attached to the spindle by offering the disk up to the spindle adapter, and applying fluid pressure to the spindle fluid pressure port to cause the piston to clamp the disk against the opposing surface. The disk can then be spun up on the spindle.
