Abstract:
A disc drive comprising:at least one disc having an outer edge; an actuator; at least one head gimbal assembly operably connected to the actuator: at least one load beam, each one of the load beams extending from each one of the head gimbal assemblies away from the actuator; and a ramp located beside the outer edge of the at least one disc, the ramp comprising: at least one fixedly extending ramp tooth; and at least one surface of one of the ramp tooth configured for abutment by one of the load beams, wherein the surface comprises: a proximal surface; a distal surface, the distal surface being relatively further away from the at ;least one disc than the proximal surface; and a transition surface between and adjacent to the proximal surface and the distal surface, wherein the transition surface is configured to block the load bear from moving from the proximal surface to the distal surface.
