Abstract

The present invention provides a method for manufacturing a magnetic- disk glass substrate with which a surface roughness of a main surface of a glass substrate can be reduced more than with currently available methods, and the number of surface defects can also be significantly reduced. The method for manufacturing a magnetic-disk glass substrate of the present invention includes processing for reducing a roughness of a main surface of a glass substrate using a treatment liquid containing organic particles made of a styrene-based resin, an acrylic resin, or a urethane-based resin, for example, as abrasive particles. In order to reduce the number of defects resulting from foreign matter attaching to the surface of the glass substrate after the processing, organic particles are classified in order to reduce the number of particles that are included in the organic particles and have a particle diameter of 3 ?m or less.
