  • Magnetic disk having separate park and take-off zones
    Patent number: 5959814
    Abstract: A disk configured to store magnetically readable data is comprised of three distinct annular regions: a parking zone, a take-off zone, and a data storage area. The parking zone is heavily textured or roughened on the order of about 1 microinch, but the take-off zone is only lightly textured or roughened. A transducer head is located over the parking zone when the rotational speed of the disk is relatively slow. Once the rotational speed increases above this minimal value, the transducing head is moved to the take-off zone until the speed of the disk approaches the desired operating speed.
