Abstract

The present invention provides a method for manufacturing a magnetic-disk glass substrate that can reduce cleaning residue of abrasive particles and sufficiently reduce substrate surface defects. In the present invention, a main surface of a disk-shaped substrate is polished by holding the disk-shaped substrate between a pair of surface plates that have surfaces provided with polishing pads and supplying a polishing liquid containing colloidal silica as abrasive particles to a surface to be polished. The polishing liquid contains, as an additive, a specific substance that has an amide group or a urea group and is represented by General Formula I: General Formula I R1-NH-CO-R2 where R1 represents an alkyl group or a hydrogen atom, R2 represents an alkyl group or -NH-R3, and R3 represents an alkyl group.
