摘要： A texture treatment for a carbon substrate of a magnetic disk or for a carbon overcoat layer of a magnetic disk is effective to prevent the generation of a stiction phenomenon between a magnetic head and the surface of a magnetic disk. The texture treatment for a carbon substrate or carbon overcoat of a magnetic disk involves the steps of: preparing the carbon disk surface; forming a catalytic material layer on the surface; and performing a heat treatment of the disks in an oxidizing atmosphere. Preferably, islands of catalytic material are formed on the surface by sputtering, and a laser heat treatment is used in an oxidizing atmosphere.
