PROBLEM TO BE SOLVED: To provide a manufacturing method and apparatus of a glass substrate for a magnetic recording medium by which dust generation due to contact of a substrate carrier with a rack for holding the substrate carrier can be prevented when the glass substrate is polished and then immersed in a washing liquid to be washed. SOLUTION: In the manufacturing method and apparatus of the glass substrate for the magnetic recording medium, when the glass substrate is polished using abrasive grains and then immersed in the washing liquid to be washed, a member of a fluororesin or an acetal resin is attached to either one contact part of the substrate carrier for washing and the rack for holding the carrier or both contact parts of the carrier and the rack to perform washing treatment.
