| titleOfInvention | Polycrystalline silicon substrate for magnetic recording media, and magnetic recording medium |
| abstract | The proportion of {100} crystal faces, the polish rate of which is relatively high during crystal machining, and/or the proportion of {111} crystal faces, the polish rate of which is relatively low during crystal machining, to the total area (S 0 ) of a substrate surface, is set to fall within an appropriate range. Specifically, the proportion of the total area (S {100} ) of the {100} crystal faces among crystal faces of individual crystal grains which appear on a major surface of a polycrystalline silicon substrate to the total area (S 0 ) of the substrate surface, is set not less than 10% and less than 50%. Such crystal face selection makes it possible to reduce the scale of “steps” formed due to the crystal face index dependence of polish rate, thereby to give a planar and smooth substrate surface. |
