The present invention relates to a device for reading from 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.
