摘要： An apparatus and a method for controlling drive tracks of a light-scribe disc are provided to perform accurate drive track control by adding an offset value to drive voltage to compensate. A method for controlling drive tracks of a light-scribe disc includes the steps of determining a magnetic track drive offset value based on control feature information of a light-scribe disc, and controlling the magnetic track drive based on the offset value while printing a label image(S17). The magnetic track drive offset value is determined by verifying the type of the light-scribe disc and the current location of a focus lens and searching for the corresponding offset value from track drive offset information stored previously.

摘要： The invention relates to a suspension arm actuator for an optical scanning device, comprising a suspension arm designed as a two-arm lever and mounted between the lever arms such that it can be pivoted about an axis extending perpendicularly thereto. On its end side, one of the lever arms supports a scanning head and comprises an articulated region, preferably an elastically bendable region, for a motion of the scanning head in focusing direction and perpendicular in relation to the pivot plane of the suspension arm. The other lever arm is provided with a component of a magnetic drive for a swivel motion about the axis. In addition, the suspension arm actuator comprises a magnetic drive for moving the optical head in focusing direction. As a result, the suspension arm is designed such that the latter's lever arm that supports the scanning head is designed simply and without any further functional elements and is, therefore, reduced in weight. To achieve this, the magnetic drive for moving the optical head (3) in focusing direction is allocated to the lever arm (II) which comprises a component (4) of the magnetic drive for the swivel motion about the axis (PA). The coils for the magnetic drives are, in particular, designed as printed coils (4 and 5 respectively).

摘要： PURPOSE: An apparatus and method for detecting a media id of a light scribe disc are provided to scan successive media ID fields of a saw tooth field in a fixed state of the focus lens position. CONSTITUTION: A controller confirms the duty ratio of a detected defect signal while scanning of a saw tooth field(S12). The final saw tooth within the saw tooth is detected while moving the focus lens position of an optical pick-up in order to make a duty ratio 50% to 50%(S13, S14). If the final saw tooth is detected, the controller detects a media ID through a successive media ID field scan of the saw field at the fixed state of the saw focus lens position(S15~S17).

摘要： A tracking error detecting method and an optical information reproducing apparatus using the same are provided to perform tracking error detection sensitive to the reproducing beam efficiency and thus to reduce bit error rate. An optical information reproducing apparatus comprises an optical system(110), a surrounding beam splitter(150), a beam information detector(160), first and second beam detectors(172,174), and a signal processing part(180). The optical system projects the reference beam over the current track and first and second surrounding tracks. The surrounding beam splitter divides reproducing beam formed by the reference beam into main reproducing beam and first and second surrounding beams. The beam information detector detects the beam information from the main reproducing beam. The signal processing part outputs a tracking error by dividing the sum of the first and second surrounding beam strength errors by the sum of first and second surrounding beam strengths.
