| titleOfInvention | Manufacturing method of glass substrate for magnetic disk |
| abstract | A method for producing a glass substrate for a magnetic disk includes: holding a glass base plate on a carrier; and using abrasive grains having a Mohs hardness (former Mohs hardness) of 8 or more as loose abrasive grains on a main surface of the glass base plate. An adhesion preventing layer for preventing the loose abrasive grains from adhering to a side wall surface located at an outer peripheral end portion of the glass base plate that contacts the carrier before the polishing of the main surface and the step of polishing Forming. A magnetic disk using a glass substrate for a magnetic disk manufactured by this method is unlikely to cause problems such as a head crash failure and a thermal asperity failure. |
