| 20100020659 | METHOD AND APPARATUS FOR PREVENTING DATA REPRODUCIBILITY - Provided are a method and an apparatus to prevent reproducibility of data with respect to an optical information storage medium. The method includes recording patterns with respect to the optical information storage medium using irradiated light so as prevent reproduction of the data. The patterns may cause an error or a malfunction when attempting to access the data of the optical information storage medium so as to prevent the reproduction of the data. | 01-28-2010 |
| 20110265105 | OPTICAL COLLIMATOR ASSEMBLY AND OPTICAL PICKUP DEVICE INCLUDING THE SAME - An optical collimator assembly used in an optical pickup device and an optical pickup device are provided. The optical collimator assembly may include a collimating lens, a lens holder for supporting the collimating lens, a piezoelectric element coupled to the lens holder and including a female screw portion disposed along a central axis in one direction and a plurality of pairs of piezoelectric bodies disposed symmetrically with one another around the central axis and for causing deformation in a direction that crosses the central axis, and a male screw type transfer screw coupled to the female screw portion of the piezoelectric element. | 10-27-2011 |
| 20110279625 | OPTICAL RECORDING/REPRODUCING APPARATUS HAVING LABEL PRINTER AND METHOD FOR PRINTING LABELS ON OPTICAL DISK - An optical recording/reproducing apparatus having a label printer for printing labels on an optical disk and a method for printing labels on an optical disk. The optical recording/reproducing apparatus includes an optical disk drive unit recording and reproducing information on a recording surface of an optical disk, a label printer module printing labels on a label surface of the optical disk using thermal transfer, and a controller controlling a label printing operation of the optical disk drive unit and the label printer module, wherein the label printer module includes a ribbon cartridge in which a thermal transfer ribbon to which dyes are attached is wound and which is disposed to face the label surface of the optical disk mounted in the optical disk drive unit, and a thermal printhead transferring the dyes attached to the thermal transfer ribbon onto the label surface of the optical disk using thermal transfer. | 11-17-2011 |
| 20130088947 | OPTICAL RECORDING DEVICE AND METHOD - Provided is an optical write device and method. The optical recording method includes generating a first signal including a preset write pulse power Pm in response to information to be written, generating a second signal including an over drive pulse power Po that is synchronized with the preset write pulse power Pm and which is at a higher level than the preset write pulse power Pm, and writing the information to an optical disc using a driving signal that is obtained by synthesizing the first and second signals. | 04-11-2013 |
