Summary:In this method for manufacturing a glass substrate for an information recording medium, the adsorption force of a polishing pad (410) on a glass substrate (1) is 0.50 g/cm2 to 15 g/ cm2 when slurry is supplied to the polishing pad (410). L'invention concerne un procédé de fabrication d'un substrat de verre pour un support d'enregistrement d'informations, dans lequel la force d'adsorption d'un tampon de polissage (410) sur un substrat de verre (1) est de 0,50 g/cm2 à 15 g/cm2 lorsqu'une bouillie est fournie au tampon de polissage (410).
