Abstract
Methods and apparatus for increasing the reliability of removable storage media by dynamically reducing particulate contaminants from magnetic disks. The apparatus and methods include using wipers which slidingly engage both sides of the magnetic disk as the disk rotates, in order to reduce particulates. In some embodiments, the wiper can be coupled to a swing-type actuator or to any resilient member which can be moved over the surface of the magnetic disk.
