Track Data Format/layout Patents (Class 369/275.3)
  • Patent number: 7869340
    Abstract: A visible light characteristic changing layer formed from photosensitive or heat-sensitive material is formed in a location which can be viewed from a part of a label surface of an optical disk. The optical disk is set on a turntable of an optical disk unit while the label surface of the optical disk is directed downward. The optical disk and an optical pickup are moved mutually along the plane of the optical disk. In synchronism with the relative movement, the power of a laser beam output from the optical pickup is modulated in accordance with image data, such as characters or graphic images to be printed, and the laser beam is emitted onto the visible light characteristic changing layer. As a result of the visible light characteristic changing layer being exposed to the laser beam, a visible-light reflectivity of the visible light characteristic changing layer is changed, thereby forming a image corresponding to the image data on the label surface.

  • Patent number: 7864641
    Abstract: An optical recording/reproducing apparatus includes an optical pickup unit configured to scan an optical disk with an optical signal to record and reproduce data. A power tuning unit is configured to scan a first track with the optical signal to record a first test data to the first track, while changing a power level of the optical signal within a predetermined range in sequence. A scanning time tuning unit is configured to scan a second track with an optical signal to record a second test data to the second track, while changing a scanning time within a predetermined range in sequence. A state detection unit is configured to detect a reproduction state of the first test data and second test data. A controller is configured to check the reproductions state of the first test data and second test data and determine an optimal power level and optimal scanning time. Accordingly, a write strategy is rapidly and optically tuned.
