More Information
Summary:An optical disc polishing device includes a housing in which a disc turntable assembly is arranged for carrying an optical disc on a rotation surface thereof. The housing includes a cover that carries a polishing assembly. The cover forms a slot serving as a track extending in a radial direction of the optical disc. The polishing assembly includes a positioning member, a polishing wheel, and a locking knob. A threaded section is provided on the positioning member and the polishing wheel is coupled to the positioning member to be opposite to the threaded section. The threaded section is set through the track slot to threadingly engage the locking knob in a releasable and re-tightenable manner so as to allow for position adjustment of the polishing assembly with respect to the track slot. The polishing assembly can thus be positionable to oppose a scratch formed on the disc.
