摘要：A pre-formatted optical data storage member is described in which formatzones are generated by the provision in the surface of the optical medium of a \"moth-

eye\" structure, i.e. regular surface pattern in the form of an arrangement of grooves orprotuberances. The pitch and depth of the pattern is such that when irradiated withillumination of predetermined optical characteristics, the format zones display a

reflectivity substantially lower than that of the remainder of the optical storage member.Methods of producing optical data storage members with such pre-formatting are alsodescribed.
