Reproducing information from aninformation carrier

Abstract

The invention described is an apparatus for reproducing information from an information carrier (11) comprising: a waveform equalizer (6) for obtaining a corrected signal (S′) by performing a waveform equalization to a read signal (S), the waveform equalizer (6) having an amplifying element with a gain (K); and gain setting means (1) for reading a numerical gain setting stored on the information carrier (11) and setting the gain (K) of the amplifying element to a value related to the numerical gain setting. By reading the numerical gain setting from the information carrier, the apparatus is able to set the gain (K) of the waveform equalizer to the optimal value for suppressing noise and inter symbol interference. The equalizer can be followed by a limit equalizer, the gain of which can also be wave form read from the information carrier.
