摘要： This apparatus relates to a data carrier which rotates about an axis and on which a track is provided for containing said data, said track spiraling around a center, which apparatus comprises an angle measurer for many purposes. For obtaining this angular position information, for example an eccentricity measurer is used. The eccentricity is defined by the non-coincidence of the center and the axis. Application: The invention is well suited to small-size optical discs, CD systems, DVD systems, and Blu-Ray systems.

摘要： The invention relates to an actuator position control method for use in a recorded information reproducing apparatus. Front, main and rear beams (or at least one main beam) are directed onto a recorded track formed on a rotating optical recording medium and respective first, second and third signals are produced in response to light reflected by said recorded track when it is scanned by the main beam. The control method comprises the steps of producing from a source of light said beam(s); scanning with the main beam the recorded track; controlling the position of said main beam with respect to the recorded track in response to position control signals, and reading the recorded information by means of a specific processing operation of the second signal. According to the invention, said method also comprises the steps of scanning in advance, with an additional beam arranged in such a way that it precedes the main one in the scanning direction, a portion of recorded track which is located in front of the portion of recorded track that will be later, after a predetermined delay, scanned by the main beam; and, on the basis of signals generated in response to the occurrence of possible defects, cancelling the effects of the variations of said corresponding signals, subsequent to variations of reflected light caused by said defects, by means of a modification of the position control signals for controlling the position of said main beam.
