Abstract
A cleaning disc for a media reading device having a laser lens. The cleaning disc includes a first surface configured to face the laser lens, a brush extending outwardly from the first surface, and a recess in the first surface configured to receive at least a portion of the brush when the brush contacts the laser lens during a cleaning operation. Each brush is defined by a strand of material that includes opposite ends. A first end of the material extends through a first aperture to define a first brush and a second end extends through a second, spaced apart aperture to define a second brush. A middle portion of the strand of material extends along a second surface of the cleaning disc between the first and second apertures, and is covered by a cover.
