Abstract

Provided is a method for manufacturing a magnetic-disk substrate,including polishing processing in which a disk-shaped substrate is sandwiched between a pair of polishing pads, a slurry containing polishing abrasive particles is supplied between the polishing pads and the substrate, and main surfaces of the substrate are polished by relatively sliding the polishing pads and the substrate. A plate-shaped substance having a particle diameter that is larger than an average particle diameter of the polishing abrasive particles and the polishing abrasive particles that are included in the slurry have a difference in surface charge amounts, and before the polishing processing is performed, adsorption processing for causing a solid adsorption material to be adsorbed by the plate-shaped substance in the slurry by mixing the adsorption material into the slurry is performed, the adsorption material capable of being adsorbed by at least the plate-shaped substance and having a surface charge with a sign different from that of a surface charge of the plate-shaped substance.
