Abstract:
A magnetic disc drive comprising:a base; a disc rotatably attached to said base; a curved ramp attached to the base near said disc, the ramp comprising substantially curved contact edge defined by an intersection between two surfaces; and an actuator assembly pivotably attached to said base at an actuator assembly pivot point, the actuator assembly further comprising: a suspension attached to one end of the actuator assembly; and a slider attached to said suspension, the slider being movable between a transducing position and an unload position, the suspension including a lift tab configured to contact the edge of the ramp at a contact point such that the contact point moves towards the actuator pivot point as the slider moves towards the unload position, a distance between a tip of the lift tab and the contact point continually increasing, with the contact point also being nearest to the actuator pivot point when the slider is furthest away from the disc.
