A method of manufacturing and initialising the recording layer of phase-change optical data storage disks is disclosed. The initialisation step can take place during or after the production of the disk, and is characterised in that the whole of the active layer is exposed to radiant energy simultaneously, preferably by means of a xenon flashlight. Finer grain structure is obtained in the microcrystalline structure of the recording layer than is evident in prior art techniques. |
