    摘要: A method for producing a magnetic disk having a surface roughness in the entire portion of its main surface in which the peak height of the surface roughness in a data zone of the magnetic disk is lower than the peak height of the surface roughness in a CSS zone of the magnetic disk, wherein forming a magnetic disk substrate having the main surface in which a surface roughness having a substantially uniform peak height is formed in the substantially entire portion of the main surface; conducting varnishing only to the data zone in the main surface of the substrate having the surface roughness to lower the peak height of the surface roughness of the data zone; and forming a ferromagnetic layer, a protective layer and a lubricant layer sequentially on a region of the main surface of the substrate, which includes the data zone and the CSS zone.
