Abstract:
The present invention pertains to a glass for a data storage medium substrate which contains a specific amount of each of SiO 2 , Al 2 O 3 , MgO, CaO, SrO, BaO, Li 2 O, Na 2 O, and K 2 O, in molar percentage based on the oxides, and does not substantially contain B 2 O 3  or ZrO 2 , wherein the sum of the Li 2 O, Na 2 O, and K 2 O contents (R 2 O), the molar ratio of the SiO 2  content to the Al 2 O 3  content (SiO 2 /Al 2 O 3 ), and the molar ratio of the sum of the SiO 2  and Al 2 O 3  contents (SiO 2 +Al 2 O 3 ) to R 2 O [(SiO 2 +Al 2 O 3 )/R 2 O] fall within their specific ranges, formula (1): 90<[SiO 2 ]+2×[Al 2 O 3 ]+0.8×[RO]−0.5×[R 2 O] [in formula (1), RO represents the sum of the MgO, CaO, SrO, and BaO contents] is satisfied, and the glass transition point T g , the alkali resistance, and the acid resistance fall within their specific ranges.

Claim (Index 14):
The glass according to  claim 2 , having a thermal expansion coefficient of 10\u00d710 \u22127 \u00b0 C. or higher.
