    Abstract: The invention relates to a lithium-sodium-aluminosilicate glass composition. This glass composition has a softening point of 700° C. or lower; a first temperature (1450° C. or lower) at which the glass composition exhibits a viscosity of 102 poises; a second temperature (1000° C. or lower) at which the glass exhibits a viscosity of 104 poises; and a mean thermal expansion coefficient between 30° C. and a glass transition temperature of the glass composition. This coefficient is within a range of from 90×10−7/° C. to 130×10−7/° C. The glass composition can be easily formed into a precursor of a glass article by pressing. It is possible to obtain a glass article that is chemically strengthened from the precursor by conducing alkali ion exchange.

    Abstract: In a method of manufacturing a glass substrate for a magnetic recording medium for forming a predetermined roughness, a principal surface of the glass substrate is precisely polished by the use of polishing material containing free abrasive grain. Remaining stress distribution for a portion of a polishing trace due to the free abrasive grain is generated on the surface of the glass substrate. A surface process is performed for at least the principal surface of the glass substrate by the use of hydrosilicofluoric acid. A portion having relatively high remaining distortion in the generated remaining stress distribution is decided as an island portion. The glass substrate is heated after precisely polishing before performing the surface process by the use of the hydrosilicofluoric acid.
