Abstract

A device is for scribing a visible label on the medium. The medium (), 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 () and a positioning unit () 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 () for, during at least one boundary trace of the substantially parallel traces which precedes or succeeds a head movement, temporarily applying a broadening signal () 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.
