Abstract
A method of manufacturing a magnetic disk comprises the steps of: a) providing a substrate with a layer of an amorphous multi-component material at its surface; b) irradiating the amorphous layer (e.g. by applying heat from a heating element, laser beam, or the like) to thereby create micro-structurally changed regions in the amorphous layer; and c) chemo-mechanically polishing the amorphous layer to produce micro-texture features at or near the micro-structurally changed regions. The disk is then completed by depositing additional layers such as an underlayer, a magnetic layer, a protective overcoat, etc.
