Patent ID: 8203806

Claim:
A disk drive comprising: a disk drive base; a spindle attached to the disk drive base; a disk attached to the spindle, the disk including a disk outer periphery; an actuator attached to the disk drive base; a head gimbal assembly (HGA) attached to the actuator, the HGA including a lift-tab; and a ramp including: a fixed portion that is fixed to the disk drive base; a guide portion that is not fixed to the disk drive base, the guide portion including a guide surface having a parking region that is in contact with the lift-tab with the disk drive in a non-operational state, the guide surface also having a load/unload region that extends over the disk outer periphery, the guide surface defining a guide surface length that is measured from the parking region to the load/unload region; and a torsionally-compliant member connecting the fixed portion to the guide portion, a distance between the torsionally-compliant member and the parking region measured approximately parallel to the guide surface length being less than half the guide surface length; wherein the guide portion is not connected to the fixed portion over at least two-thirds of the guide surface length, and wherein the fixed portion includes at least one limiter surface that is disposed to be contacted by the guide portion if a maximum torsional deflection of the guide portion is exceeded.
