| titleOfInvention | Manufacturing method of substrate for information recording medium |
| abstract | [PROBLEMS] To manufacture a substrate for an information recording medium having various physical properties required for a next-generation information recording medium substrate typified by a perpendicular magnetic recording method and the like, in particular, having a high fracture toughness and a smooth surface at a low cost. It is to provide a manufacturing method. A step of preparing a plate-like crystallized glass containing a SiO 2 component, an Al 2 O 3 component, and an R ′ 2 O component (where R ′ is one or more of Li, Na, and K); A grinding step of grinding the crystallized glass, the grinding step only comprising a step of grinding the crystallized glass with a diamond pad, and the grinding step comprises a diamond pad having an average diameter of diamond particles of 0.1 to 5 μm Manufacturing method of substrate for information recording medium to be ground by slab. [Selection figure] None |
