Abstract
Two data-free tracks, a takeoff zone and a landing zone, are provided on a magnetic disc, in order to provide a place for the magnetic head to come in contact with the disc without risk of destruction of data. An actuator controller places the head on the takeoff zone at the start of the disc's rotation and on the landing zone at the finish of the disc's rotation. Wear caused by contact of the head with the disc is thereby distributed over two zones, which prolongs the life of the disc.
