A glass substrate is for use in a magnetic disk. The glass substrate is formed by using a plate-like glass produced by a float method and having a pair of main surfaces. One surface of the main surfaces, which is formed with a tin layer when producing the plate-like glass by the float method, is caused to serve as a surface not for use in magnetic recording and the other surface formed with no tin layer is caused to serve as a surface for use in magnetic recording.
