Patent ID: 7969845

Claim:
An optical recording apparatus which records post pre-format recording information on an optical recording medium which has a guide portion formed in advance for guiding a light beam and a plurality of address portions for specifying individual positions of the guide portion, comprising: position information detection means for detecting position information of a recording region in which significant information is recorded along the guide portion and a breakdown region which is part of the guide portion or/and the address portions and is broken down so address information specifying individual positions of the guide portion included as pre-format information in the breakdown region cannot be detected using the light beam; servo means for controlling the position of the light beam based on the position information; and laser light intensity adjustment means for adjusting the intensity of the light beam in order to record information based on a predetermined format in the recording region and thermally break down the breakdown region such that the address information specifying the individual positions of the guide portion included as the pre-format information in the breakdown region cannot be detected using the light beam.
