A CLEANING DEVICE AND CLEANING METHOD

摘要

A cleaning device (1) for cleaning a lens (2) of a laser head (3) of a compact disc player comprises a carrier disc (5) which is substantially similar to a standard compact disc. Cleaning brushes (14 and 15) are located on the carrier disc (5) on a face (6) thereof which, in use, faces the laser head (3) for cleaning the lens (2) as the carrier disc (5) rotates in the compact disc receiving location of the compact disc player. A non-reflective band (25) is printed on and extends around the outer periphery (12) of the carrier disc (5) for returning the laser head (3) from the outer periphery (12) of the carrier disc (5) to an inner periphery (11), so that as the laser head (3) cycles between the inner and outer peripheries (11 and 12) across the brusches (14 and 15), the brushes (14 and 15) engage the lens (2) in two different relative directions for cleaning thereof.
