ABSTRACT:
A device is disclosed for reading from and/or writing to optical recording media, which has a scanner whose output is connected to the input of an analogue-to-digital converter, whose output is in turn connected to the input of a mirror signal detector. The device is able to generate a reliable mirror signal even at relatively high track crossing frequencies. The mirror signal detector has at least one element which is variable as a function of frequency.
