摘要

The present invention is directed towards a device for writing to a read and / or the medium from the optical recording medium, the device may have a scanning means, the output of the means for analog-to-be connected to the input of a digital converter 3, the the output of the converter is coupled back to the input of a mirror (mirror) signal detector (1). An object of the present invention is to provide this type of devices that can cause the mirror signal of interest is relatively reliable in high track crossing frequency. This may be achieved in accordance with the present invention due to the fact that with the mirror signal detector (1) is at least one element (11, 12, 24) that varies as a function of at least the frequency.
