Abstract
In a disc drive with a disc spun by a motor and a head positionable over the disc, a disc drive controller alternately leaves the head landed on successive landing spots in a landing zone on the disc for selected stop intervals to remove an increment of lubricant from the head with each stop and then automatically lifts the head by spinning the disc for selected run intervals between the stop intervals so the head does not stick to the disc.
