Abstract
The present invention relates to a method for controlling a LBR (Laser Beam Recorder) (56) suitable for mastering a record carrier (60) by writing data in the record carrier in circular or spiral tracks and comprising: means (58) for rotating a record carrier; means (62) for moving a laser (61) over the record carrier (60) in a radial direction with reference to the rotation of the record carrier (60); means (65) for controlling the laser output power; and means (66) for synchronizing the rotation of the record carrier (60), the movement of the laser (61) and the laser output power. In accordance with the invention synchronizing the rotation of the record carrier 60; the movement of the laser 61 and the laser output power is performed such that at least a part of the data is written in at least one track comprising a different arrangement than circular or spiral. The present invention also relates to a Laser Beam Recorder.
