Abstract

It is an object of the present invention to reliably achieve a high polishing rate with respect to a glass surface without largely depending on the chemical polishing action of an abrasive agent in a method of manufacturing a glass substrate (G) for a magnetic disk. The present method includes a step of polishing a principal face of a glass substrate (G) by causing a polisher pad (10) to slide in contact with the principal face of the glass substrate (G), and simultaneously, by supplying a polisher liquid containing loose abrasive grain onto the principal face of the glass substrate (G). The polisher pad (10) includes a plurality of slide contact portions (11) and at least a groove (12) on a face thereof. The slide contact portions (11) are slid in contact with the principal face of the glass substrate (G). Each groove (12) is disposed between adjacent two of the slide contact portions (11). Further, the total edge length of the slide contact portions (11) formed on the face of the polisher pad (10) per square meter is set to be equal to 200 meters, while a filling ratio is set to be greater than or equal to 80 % where the filling ratio is defined as a ratio of the area of the slide contact portions (11) with respect to that of the entire face of the polisher pad (10).
