<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a substrate for a magnetic disk that efficiently polishes one main surface of a substrate for single side recording. <P>SOLUTION: The method for manufacturing a substrate for a magnetic disk includes a polishing process for polishing disk-shaped substrates by the use of a polishing machine having a carrier 5 held between a pair of polishing surface plates 1 and 2, which revolves and rotates while holding a plurality of the disk-shaped glass substrates 4. In the polishing machine, the carrier 5 is placed while a plate-like member 10 is disposed on one side of main surfaces, so that only the other side of the main surfaces of the disk-shaped glass substrates 4 is polished so as not to polish the one side of the main surfaces of the disk-shaped glass substrates 4. <P>COPYRIGHT: (C)2011,JPO&INPIT |
