<p>In a method of manufacturing a magnetic-disk glass substrate, the method including a process of polishing a main surface of a glass substrate using a polisher, the polisher has a pH of 4 to 6 and contains polishing particles, a dispersion medium serving to disperse the polishing particles, and an additive serving to increase an electrolyte concentration in the polisher without changing the pH of the polisher, thereby performing polishing using the polisher.</p> |
