ABSTRACT:
System and method are devised to produce an optical recording medium suitable for identification and management. A recording layer formed in the optical recording medium is irradiated with writing light by a pickup. A visible image pattern suitable for identification, management or the like is formed on the optical recording medium by generating changes in optical characteristics of a portion irradiated with light and a portion not irradiated with light in the recording layer.
