Abstract:
A disk drive, comprising:a rotatable storage disk;a slider, including an air bearing surface (ABS) and a transducer for reading information stored on the disk;a channel electrically coupled to the transducer for processing the information read from the disk;an actuator assembly coupled to the transducer via a suspension for positioning the transducer relative to the disk;a load/unload structure disposed at the perimeter of the disk, comprising,a load/unload ramp for engaging a distal end of the suspension; anda limiter extending from the ramp, including a cleaning surface disposed such that when the distal end of the suspension has engaged the ramp, the cleaning surface comes into contact with the ABS and removes particles therefrom;a servo control system for controlling movement of the actuator assembly, wherein the servo control system dithers the slider for at least some of the time when the ABS is in contact with the cleaning surface;a housing;an air filter; anda baffle around the disk disposed between a perimeter of the housing and the ramp such that airflow generated by the rotatable disk is directed over the cleaning surface and toward the air filter.
