ABSTRACT:
A device for cleaning a gramophone record while the record is being played comprises an endless belt arranged to carry an electrostatic charge and mounted so as to extend generally radially of the record, with a lower run of the belt in contact with the record surface. During rotation of the record the belt gathers and removes dust and other particles from the record surface, the particles being retained on the belt by the electrostatic charge. The belt is driven by rotation of the record to transport the particles to a position remote from the record surface, the particles being removed from the belt at this position.
