Abstract:
1. An optical disk restoration apparatus comprising: a) a rotatable object holder for holding an object to be polished; b) a turret for holding multiple polishing bodies during polishing operations; c) a turret driver for rotating the turret between polishing operations to interchange between polishing bodies being positioned opposite the object to be polished; d) a linking mechanism for holding one of the polishing bodies while allowing the polishing body to rotate; e) a pressing/separating means for pressing or separating the object to be polished and the polishing body held by the linking mechanism onto or from each other; f) a driver for rotating the linking mechanism; g) a rotating controller for regulating the rotation of the rotatable object to be polished; and h) a linking part connecting the rotation controller and the object holder inserted through a cavity of a shaft of the turret, wherein the driver is a single driver including means for selectively coupling to each of the multiple polishing bodies when the turret positions each of the multiple polishing bodies opposite the object to be polished.
