CLOTH AND METHOD FOR POLISHING MAGNETIC RECORDING DISK

摘要

PROBLEM TO BE SOLVED: To provide a cloth and method for polishing efficiently a magnetic recording disk base without forming any partially deep flaw. SOLUTION: Single-yarn filament yarn of multi-filament yarn of <=0.3 denier used for cloth has a tilt of >=10 deg. to the length of polishing cloth by both the tilt of a warp of sateen weave or leasing weave and the tilt of twine, and in a polishing process which uses diamond slurry in combination, diamond grains are scattered uniformly over the entire surface of the polishing cloth to permit uniform and efficient polishing.
