Abstract

A system and method effectively cleans head assemblies and data storage disks without damage. In one embodiment, the system includes a cleaning pad and a head disposed within a disk drive. An actuator is placed in communication with the head such that the actuator can produce two independent movements of the head. One of the independent movements may include reciprocal movement of the head while it is proximate the cleaning pad. Alternatively, or in addition to the reciprocal movement, the actuator may vary the amount of force exerted on the head by the cleaning pad. In an alternative embodiment, a cleaning system for removing contaminants from a removable data storage disk includes a housing adapted to receive the disk and a cleaning pad rotatably mounted within the housing proximate the disk to remove the contaminants from the disk. The system further includes a pad-cleaning component in communication with the cleaning pad such that the contaminants are removed from the pad.
