An optical disk restoration apparatus and optical disk restoration method are provided, which are capable of achieving a high level of capability of restoring a scratched optical disk, without consuming the time and labor of an operator, while reducing the production cost of the apparatus. During a polishing process, an appropriate amount of a polishing agent is dropped onto the readout surface of the optical disk by a polishing agent supply pump to continuously supply the polishing agent to the interface between the optical disk and polishing pads, while a polishing water supply pump is operated to replenish the polishing agent with moisture evaporated by the polishing heat. By this mechanism, the amount and physical properties of the polishing agent at the interface between the optical disk and the polishing pads are appropriately maintained for a long period of time, so that the restoration capability is maintained at high levels.
A dry-type optical disk restoration apparatus for polishing a readout surface of an optical disk to be restored, by rotating a polishing pad holding a polishing agent and the optical disk relative to each other in a contact state, comprising:
An optical disk restoration method including a dry polishing process for polishing a readout surface of an optical disk by rotating a polishing pad holding a polishing agent and the optical disk relative to each other in a contact state, wherein the polishing process includes:
