摘要 |
The invention concerns a method and a device for initialising a phase-change recording medium which consists in heating the phase-change medium to be initialised by sweeping the surface of said medium with a light source. The invention is characterised in that the laser source consists of at least an extended light source emitting at least a beam directed towards an optical element providing it with convergence in a single heating zone, with a single intensity profile shape. The invention also concerns the recording products resulting from said method. |
