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.
Claims14
An information recording system for recording information in an optical recording medium comprising:
- a driving part for driving the optical recording medium;
- and
- a writing part for forming a visible image pattern by irradiating a recording layer formed in the optical recording medium with light to generate changes in optical characteristics of a portion irradiated with the light and a portion not irradiated with the light in the recording layer.
An information recording method for recording information in an optical recording medium comprising the steps of:
- irradiating a recording layer formed in said optical recording medium with light;
- and
- generating changes in optical characteristics of a portion irradiated with the light and a portion not irradiated with the light in said recording layer to form a visible image pattern.
