ABSTRACT:
A data storage system has a disk having a first, second and third zone. The first zone has rough texturing to prevent stiction between a slider at rest and the disk. The second zone has intermediate texturing to prevent stiction when a moving slider is in contact with the disk. The third zone has a smooth texture and is used for data recording. A control unit moves the slider between the zones as appropriate on power up and power down of the system. The system has an actuator latch having a bias device. The bias device allows the slider to be positioned between the first and second zones by selective energizing of the actuator while in the latched position.
