Abstract
An apparatus for scanning a track on a record carrier has a head () and front end circuitry () for scanning the track and generating scanning signals. A detection unit () detects anomalies in the scanning signal, for example for adjusting a tracking servo. The detection unit () calculates a mean value of the scanning signal and compares the mean value to a threshold for providing an anomaly detection signal (). Further a classification unit () provides an indication of the type of defect for determining a suitable responsive or corrective action.
