摘要： In an apparatus for reading from and/or writing to an optical recording medium (7), it is desirable, in particular in the case of track jumps, to detect the direction of the track jump, i.e. the direction of movement of an objective lens (6) of the apparatus relative to the optical recording medium (7) in order to be able to carry out corresponding track regulation. For this purpose, and also for determining the number of tracks crossed by the scanning beams (14-18), it is proposed to determine the number of zero crossings and also the phase difference between at least two error signals derived from the reflected scanning beams.

摘要： The present invention relates to a device for reading from and/or writing to recording media in disc form which has an unbalance compensation means.
The object of the invention is to propose a device of this type which has the smallest possible unbalance even when exchangeable recording media are used.
This object is achieved according to the invention by virtue of the fact that the unbalance compensation means is a centrifugal force generation means which generates a centrifugal force which is variable during operation. According to another aspect of the present invention, provision is made for the unbalance compensation means to be a positioning means for positioning the recording medium.
The field of application of the invention includes, inter alia, devices for reading from and/or writing to optical recording media such as CD, CD-ROM, DVD, DVD-ROM, DVD-RAM and the like.
