<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a substrate for a magnetic disk for easily and surely smoothing an outer peripheral end part of the substrate. <P>SOLUTION: In this method, the surface of the substrate is polished by sliding abrasive cloth 12 in a pressurized state on the surface of the disc-shaped substrate 1, while fitting and holding the substrate 1 into a circular carrier hole 25 of a carrier 200. A diameter difference of the carrier hole 25 from the substrate 1 is set to be 0.5 to 1.0 mm. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
