Abstract
A gamma irradiated load/unload ramp for a disc drive, the load/unload ramp having a hardened surface that increases the wear properties of the ramp, i.e., reduces debris formation in the disc drive housing that results from the sliding interaction between the load/unload ramp and actuator arm. Typically, the load/unload ramp is hardened through the absorption of about 0.05 to 0.5 Mrad radiation. A method of reducing debris formation in a disc drive having a load/unload ramp includes treating the load/unload ramp with gamma radiation.
