A method for manufacturing a magnetic disk comprises the step of depositing a metallic layer on a glass substrate and laser texturing the metallic layer. The magnetic disk is then completed by deposition of (a) an underlayer such as Cr or sputtered NiP, (b) a magnetic layer such as a Co or Fe alloy, and (c) a protective overcoat such as ZrO2, carbon or hydrogenated carbon. By providing the above-mentioned metallic layer, laser texturing can now be used in conjunction with glass substrates. |
