Abstract
An arrangement for reading information from a record carrier, such as in a HDD, include a read head (R ), an amplifier ( ) for amplifying the signal read by the read head, an equalizer ( ) for equalizing the signal read by the read head, and a bit detector ( ) for detecting bits in the signal read by the read head. The invention, the arrangement further comprises a DC correction unit ( ) for subtracting a correction value from an input signal in response to an error signal so as to obtain a DC corrected output signal. The bit detector ( ) detects a sequence of bits based in the DC corrected output signal. Further, an error signal generating unit ( ) is present for generating the error signal in response to the DC corrected output signal and the sequence.
