Disk drive having a head loading ramp and a disk limiter tab that projects from a side of an actuator arm

摘要

A disk drive includes a disk drive base, and a spindle. A disk is attached to the spindle, and the disk includes a disk outer peripheral extent. An actuator is attached to the disk drive base and defines an actuator pivot axis that is substantially parallel to the spindle rotation axis. At least one actuator arm extends away from the actuator pivot axis. A head gimbal assembly (HGA) is attached to the at least one actuator arm. A first disk limiter tab protrudes from a side of the actuator towards the spindle rotation axis. The disk drive also includes a ramp that has a parking surface that is in contact with the HGA with the disk drive in a non-operational state. The first disk limiter tab extends over the disk outer peripheral extent in the non-operational state.

1. A disk drive comprising:
a disk drive base; a spindle attached to the disk drive base and defining a spindle rotation axis; a first disk for storing user data and attached to the spindle, the first disk including a disk outer peripheral extent; an actuator attached to the disk drive base and defining an actuator pivot axis that is substantially parallel to the spindle rotation axis, the actuator including:
at least one actuator arm extending away from the actuator pivot axis; anda first disk limiter tab protruding from a side of the actuator towards the spindle rotation axis; wherein the disk drive further comprises: a head gimbal assembly (HGA) attached to the at least one actuator arm; and a ramp comprising a parking surface that is in contact with the HGA with the disk drive in a non-operational state, wherein in the non-operational state, the first disk limiter tab extends over the first disk from the disk outer peripheral extent toward the spindle rotation axis by only a radial overlap distance in the range of 0.2 mm to 2 mm.
