Abstract:
1. An optical disc recording apparatus for forming by a laser beam of substantially constant power an image on an optical disc, which includes a recording face for recording data and a label face for forming an image disposed on an opposite side of the recording face, address information specifying an irradiation radial position, the address information being included in the recording data and wherein no address information is recorded on the label face, the apparatus comprising: an optical pickup which applies the laser beam of substantially constant power to the optical disc, wherein when the optical pickup is opposed to the recording face, the optical pickup records the data on the recording face, and when the optical pickup is opposed to the label face, the optical pickup forms the image on the label face; a rotating section which rotates the optical disc at a substantially constant speed; a feeding section which moves the optical pickup by a movement distance in a radial direction of the optical disc; a detecting section which detects a radial position of the optical pickup with respect to the optical disc; and a movement distance controlling section which changes the movement distance set by the feeding section in accordance with the radial position of the optical pickup detected by the detecting section when forming the image on the label face, wherein the optical pickup, the rotating section, the feeding section and the detecting section are used for both data recording on the recording face and image forming on the label face.
