| titleOfInvention | Method of Producing Glass Substrate for Information Recording Medium |
| abstract | Disclosed is a method of producing a glass substrate for an information recording medium including a precision polishing step of using a polishing material containing colloidal silica and performing precision polishing, under acidic conditions, on a glass material in which the amount of iron adhered on the surface is 0.5 ng/cm 2 or less and the surface roughness Ra is 1 nm or less. Additionally disclosed is a glass substrate for an information recording medium produced by the foregoing method of producing a glass substrate for an information recording medium. |
