Patent ID: 8797677

Claim:
A disk drive comprising: a disk having a bottom surface; a head gimbal assembly (HGA); an actuator to move the HGA in relation to the disk; a base comprising: a first surface lying along a first plane; a first base step and a second base step adjacent the first surface for allowing clearance for movement of the actuator or the HGA; a second surface lying along a second plane positioned substantially parallel to the first plane, the second surface being adjacent to both the first surface and the first base step and spaced apart from the first surface between the first surface and the first base step, wherein the second surface is located beneath at least a portion of the bottom surface of the disk; and a third surface lying along a third plane positioned substantially parallel to the first plane, the third surface being adjacent to both the first surface and the second base step and spaced apart from the first surface between the first surface and the second base step, wherein the third surface is located beneath at least a portion of the bottom surface of the disk; and wherein the disk drive further comprises: a first damper located on the second surface and configured to contact a portion of the bottom surface of the disk when the disk is deflected toward the first surface so as to reduce deformation of the disk; and a second damper located on the third surface and configured to contact a portion of the bottom surface of the disk when the disk is deflected toward the first surface so as to reduce deformation of the disk.
