Method and apparatus for cleaning disks containing encoded information
First Claim
1. Apparatus for cleaning disks containing encoded information, such as phonorecords and videodiscs, comprising:
- a first roller having a core and an electrostatically activatable, mechanically chargeable outer surface adapted to be rolled over a surface of the disk to be cleaned, said outer surface being composed of a permanently tacky soft, flexible silicone polymer having a Shore A durometer hardness of less than approximately 100, said outer surface being cleanable by rolling it over a second surface covered with a pressure sensitive adhesive;
a handle to which the first roller is secured for rotation about its axis; and
means for simultaneously cleaning and charging said first roller comprising a second roller supported by said handle for rotation about its axis in continuous rolling contact with said first roller and driven thereby, said second roller having an outer covering of pressure sensitive adhesive around the entire circumference thereof.

Abstract
A roller having a core of natural rubber and an electrostatically activatable, mechanically chargeable outer surface is secured to a handle for rotation about its axis. The outer tacky surface is composed of a soft, flexible, open-air cured silicone polymer having a Shore A durometer hardness of approximately 30. The tacky outer surface is not caused by sticky adhesive but is permanent and formed during the curing process. The outer surface is mechanically chargeable and cleanable by rolling the surface over a second surface covered with a pressure sensitive adhesive. The second surface in one embodiment is the outer surface of a second roller which is biased into contact with the outer surface of the first roller as the first roller is rolled over the surface of a disk to be cleaned.
