Abstract
A blade-type disk cleaner system for removing fine dust or greasy contamination from disks is disclosed. In one embodiment, the blade-type disk cleaner includes a cleaning blade having a length of approximately the radius of the disk, for scraping debris off the disk. The cleaning blade is positioned to contact the surface of the disk at approximately 30 to 45 degree contact angle, and the top angle of the cleaning blade is approximately 15 to 25 degrees. A control unit is coupled to the cleaning blade and is used to raise and lower the blade to the rotating disk. In some embodiments, a dust collection element is used to collect debris scraped from the disk by the cleaning blade. In one embodiment, a smaller blade is used. A radial movement mechanism moves the cleaning blade across the radius of the rotating disk, allowing non-flat disks to be cleaned. A cleaning pad is used to clean debris from the cleaning blade. A brush can be added to the system so that the radial movement mechanism first moves the brush across the radius of the disk and then, if necessary, moves the cleaning blade across the disk's radius. The entire disk cleaning system can be integrated within the disk drive unit.
