粗面としたことを特徴とするガラス製記録媒体。 When a rotating glass recording medium is held under pressure by a rotating drive shaft, information is recorded and reproduced on the surface of the glass recording medium by a magnetic head that floats a minute amount, and the glass recording medium is stopped. In a glass recording medium of a magnetic disk device in which a magnetic head contacts the surface of the glass recording medium, the surface to be held under pressure is a mirror surface, and at least the area other than the mirror surface area is roughened within the movement range of the magnetic head. A glass recording medium characterized by a flat surface.
