Method and apparatus for forming a label

In an optical disc drive, adapted for forming a label on the label side 14 of a recordable optical disc 10, a determination of the rotation angle provided, so that the marking of the label side 14 can be synchronized upon. The method to determine the rotation angle is based upon one or two of the signals 17', 18', 19' geneed by the Hall-effect elements 17, 18, 19 which are normally present in an optical disc drive and are used to generate the tacho signal 24. Advantageously, the actual relationshp between rotation angle a and the amplitude of these signals is recorded in a calibration pedure, so as to allow for a higher precision of the rotation angle determined. This calibraon procedure may be performed in the factory or by the user, and may not require any ditional ad-hoc equipment if a synchronization pattern present in an optical disc is used.
