Abstract
An apparatus for cleaning record disks in which the disks are held by a turntable and rotated beneath a mechanism that imparts an electrostatic charge to dust particles on the information bearing surfaces. The charged and thus loosened particles are removed by a vacuum device. A blower and an attraction member charged oppositely to the particles further enhance the cleaning action of the vacuum.
