A load/unload ramp includes a body with ramps, load/unload surfaces, and a vertical wall. The ramps include outer grooves positioned between the ramps. The load/unload surfaces extend from the respective ramps. The vertical wall includes channels extending through the vertical wall. In embodiments, the channels are positioned between the load/unload surfaces.

Load/unload ramps with channels

Examples of slide-in ramps for hard-disk drives are disclosed. In one example according to aspects of the present disclosure, a slide-in ramp includes: a ramp body, a head load/unload section connected to the ramp body, and a slot defined in the ramp body. The slot includes a first portion and a second portion. A first upper surface of the ramp body surrounds the first portion of the slot at a top side of the ramp body, and a second upper surface of the ramp body surrounds the second portion of the slot at the top side of the ramp body. The second upper surface is non-coplanar with the first upper surface according to various examples.

Retaining slide-in ramp for hard disk drive

An arm assembly for a disc drive. The arm assembly has a load arm for supporting a slider and has a lift tab with a ramp-engaging region for parking the load arm when not in use. This ramp-engaging region has an outer surface defined by a first radius and a second radius different than the first radius.
