With current magnetic disk and head slider technology, the lubricant applied to the buffed oxide disk coatings plays a special role of surface protection when start-stop operation with heads loaded is involved. The lubricant is effective also when, due to access mechanism shock or disk surface irregularity, momentary contact takes place between slider and disk surfaces. Damage to surfaces and hard errors are thus prevented.
