发明名称 MANUFACTURING METHOD FOR GLASS SUBSTRATE FOR INFORMATION RECORDING MEDIUM, AND INFORMATION RECORDING MEDIUM
摘要 <p>A carrier (500) has a plurality of auxiliary through holes (530). If the radius of the carrier (500) is Rmm, and the distance from the center position (C1) of the carrier (500) to the center position (C2) of the auxiliary through holes (530) is rmm, at least one of the through holes (530) is provided in a position that satisfies the following relational expression: [r>=(3/4)×R]. Furthermore, if the diameter of a glass substrate is Dmm, the diameter of the auxiliary through holes (530) is at least 1mm less than Dmm.</p>
