摘要： A device is for scribing a visible label on the medium. The medium (11), for example an optical disc, has a label side provided with a radiation sensitive layer for creating the visible label via a beam of radiation. The device has a head (22) for providing the beam and generating a detector signal in dependence of radiation reflected from the medium, and a focus unit (32) for generating a focus control signal for focusing the beam. A label control unit (33) controls the scribing in dependence of label data. The focus unit (32) detects a focus error by including a focus excitation signal in the focus control signal and detecting a deviation in the detector signal in dependence of the focus excitation signal. The label control unit (33) is for controlling the focus unit in dependence on the label data to detect the focus error during said scribing and without interrupting said scribing.

摘要： A device is for scribing a visible label on the medium. The medium (11), for example an optical disc, has a label side provided with a radiation sensitive layer for creating the visible label via a beam of radiation. The device has a head (22) and a positioning unit (25) for radially positioning a scribing spot, which unit has a course positioning system by movements of the head and a fine positioning system. The device has a generator unit (32) for, during at least one boundary trace of the substantially parallel traces which precedes or succeeds a head movement, temporarily applying a broadening signal (35) to the fine positioning system for broadening the boundary trace in the transverse direction. This has the advantage that unwritten annular areas called white bands, which may occur due to mismatch of the head movement and the fine positioning system, are reduced or prevented.

摘要： An apparatus for scanning a track on a record carrier has a head (22) and front end circuitry (31) for scanning the track and generating scanning signals. A detection unit (32) detects anomalies in the scanning signal, for example for adjusting a tracking servo. The detection unit (32) calculates a mean value of the scanning signal and compares the mean value to a threshold for providing an anomaly detection signal (33). Further a classification unit (34) provides an indication of the type of defect for determining a suitable responsive or corrective action.
