<p>Provided is a method for manufacturing glass substrates for information-recording media with which variation in the shape of the glass substrates within a single carrier can be limited by performing strict temperature control of the surface plate. The polishing process is performed so that during the polishing process, (T1)(°C), which is the mean of the polishing pad temperatures near the sun gear and near the internal gear of the polishing surface plate, and the temperature (T2)(°C) of the polishing pads at the centers of the carriers of the polishing surface plate satisfy formula (1). |(T1)-(T2)|≤3°C (1)</p> |
