Load/unload method for sliders in a high speed disk drive
摘要:
An information handling system, such as a disk drive, includes a base, a disk stack rotatably attached to the base, and an actuator assembly movably attached to the base. The actuator assembly also includes a load spring and a slider attached to said load spring. A ramp is also attached to the base near the disk stack. The ramp is used to load and unload the sliders to and from the disk. The slider and load spring are attached to form a gimballing connection between the slider and the load spring. The disk drive also includes a spindle motor and spindle motor controller for rotating the disk at a first rotational velocity and for rotating the disk at a second rotational velocity. The slider includes an air bearing surface. Landing pads, made of a durable material such as diamond like carbon, are formed on the air bearing surface of the slider. A method for loading a slider from a ramp to a disk surface includes rotating the disk at a first rotational velocity, as the slider is loaded. The disk is rotated at a second rotational velocity after the slider is positioned over the disk. The first rotational velocity is slower than the second rotational velocity so that damage due to contact between the disk and slider is minimized.
