摘要
The present invention relates to a method for controlling a dual-beam 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 dual-beam 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 dual-beam laser output power; and means (66) for synchronizing the rotation of the record carrier (60), the movement of the dual-beam laser (61) and the dual-beam laser output power.;In accordance with the invention synchronizing the rotation of the record carrier 60; the movement of the dual-beam laser 61 and the dual-beam 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 dual-beam Laser Beam Recorder adapted to carry out the method of the invention, and to the use of such a dual-beam Laser Beam Recorder to create a high density relief structure which at least in sections comprises a different arrangement than circular or spiral.
