Method for manufacturing glass substrate for information recording medium and method for manufacturing information recording medium |
| abstract |
PROBLEM TO BE SOLVED: To obtain a glass substrate for an information recording medium having a high smoothness without defects by completely removing polishing residue by a strong acid treatment and preventing the occurrence of surface roughness due to a strong acid treatment. SOLUTION: The method for manufacturing a glass substrate for an information recording medium, comprising a step of performing a strong acid treatment after polishing a main surface of a glass substrate using polishing abrasive grains, wherein the polishing abrasive grains are used as the abrasive grains. Reacts with the processing solution components used in the process, A step of removing abrasive grains adhering to the main surface of the glass substrate before performing the strong acid treatment by using a substance having a content of a causative substance that generates a component that erodes the surface of the glass substrate is equal to or less than a predetermined amount.
