Method of polishing disks

摘要

A method of preparing for a disk polishing operation includes providing a polishing machine having a first and a second superposed platen. A first polishing pad is on the first platen and a second polishing pad is on the second platen. A plurality of carriers are disposed between the first and second polishing pads. Each carrier is adapted to rotate relative to the polishing pads and is adapted to carry at least one glass disk. A pressure, temperature and rotational speed of the polishing machine used during a disk polishing operation are determined. A number of diamond disks are provided. A diamond disk is placed in respective ones of the carriers. The polishing machine is operated at or near the determined pressure, temperature and rotational speed while simultaneously dressing the respective surfaces of the polishing pads using the diamond disks.
