A disk drive having a translatable ramp is disclosed. The disk drive includes a head gimbal assembly having a proximate end that is attached to an actuator, and a distal end that includes a lift tab. The ramp includes a lift tab supporting surface located as close to a pivot axis of the actuator as is the lift tab. The ramp also includes a ramp guiding surface that is in contact with a mating surface of the disk drive base. A fastener selectively allows or prevents relative translation between the ramp and the disk drive base. The aforementioned contact constrains the relative translation so that the relative translation changes the distance between the lift tab supporting surface and the disk axis of rotation more than the relative translation changes the distance between the lift tab supporting surface and the actuator pivot axis.
