    摘要: There are provided a method of processing an amorphous material which is capable of forming surface projections of uniform height in desired positions on the amorphous material, and a magnetic disk substrate using the amorphous material. A predetermined pressure is applied to selected parts of a surface of an amorphous material using fine particles having a hardness higher than that of the amorphous material to form high-density compressed layers, and a surface layer of the amorphous material is removed using a treatment agent that has a different removal capacity in the compressed layers and a remaining uncompressed layer, thus making the compressed layers project out. For example, the treatment agent may be an etching solution having a different etching rate in the compressed layers and the uncompressed layer.

    摘要: There is provided a substrate for information recording media and a manufacturing method thereof, which allow an information recording medium to be driven reliably and stably even when the flying height is made lower than conventionally to cope with increased recording density of the data zone. Precision polishing is carried out on a glass substrate using a polishing agent. After the precision polishing, surface treatment is carried out using an etching liquid containing both hydrofluoric acid and a fluoride salt.
