ABSTRACT:
A polishing cloth has a base material of a woven cloth formed by weaving in woven bundles of plastic fibers and its surface layer is formed by portions of these woven bundles which are cut and raised from a surface. When such a polishing cloth is used for texturing a target surface of a disk substrate, the target surface is rubbed by such a cloth while a liquid slurry containing free abrasive particles are supplied to the surface.
