  • Patent number: 7460455
    Abstract: A method used in an optical storage device having a pickup head. The pickup head includes an object lens, a first and a second light source. The object lens focuses the laser light generated by the first or the second light source onto a first or a second focal point. A driving control effort is used to change the location of the object lens. The method includes the following steps: providing the driving control effort to move the object lens; measuring a first parameter when the first focal point passes through a predetermined layer of an optical disc; measuring a second parameter when the second focal point passes through the predetermined layer of the optical disc; and (d) determining the relationship between the difference of object lens location and the driving control effort according to the predetermined distance, the first parameter, and the second parameter.

  • Publication number: 20070081434
    Abstract: Apparatuses and methods for controlling the quality of writing an optical storage medium in an optical storage system having an accessing logic for steering data to be written onto or read from the optical storage medium. The apparatus contains a halting controller, an evaluation device, a recording tangential velocity (RTV) adjusting device, and a starting controller. The halting controller requests the accessing logic to halt a write procedure at a stopping point. The evaluation device evaluates the writing quality of a portion of the data recorded onto the optical storage medium to generate an evaluation result. The RTV adjusting device requests the accessing logic to adjust the RTV of the optical storage medium if the evaluation result does not satisfy predetermined criteria. Finally, the starting controller requests the accessing logic to restart the write procedure to continue writing data onto the optical storage medium.

  • Publication number: 20050066228
    Abstract: An error compensation method and apparatus for an optical disk drive is disclosed, in which the error compensation method comprises the following procedures. First, an error signal showing the deviation of a focal point of the optical disk drive from a track is detected, and an error signal between the sledge and the actuator may also be detected, so as to produce the first sledge driving signal. Secondly, the error signal of the focal point deviating from the track, the error signal between the sledge and the actuator, the first sledge driving signal or their combination is/are selected as the basis for the sledge compensation, and the second sledge driving signal is generated according to the magnitude(s) of the selected signal(s). Subsequently, the second sledge driving signal is intermittently used for driving the sledge for error compensation.
