A ramp mechanism for a storage device reduces power consumption during head loading/unloading operations, and reduces magnetic disk drive failure due to generation and dispersion of wear powder generated by head loading and unloading operations. Wear powder is accumulated in longitudinal grooves in the ramp mechanism. A lateral groove can be provided at the head entry/exit end of the ramo mechanism to capture wear powder, if desired. The grooves are separated by wall parts having flat, tip-shaped or semi-circularly shaped tops, and the tops can extend partially over the grooves, if desired, to trap powder which falls into the grooves.
