Abstract: A method for constructing an optical disk and a method of signal detection which permits a read only device, such as a CD-ROM or DVD-ROM reader, to create a permanent mark on a disk in such a way that it can be subsequently determined that the disk had been previously accessed is disclosed. Such a disk facilitates the operation of CD-ROM or DVD-ROM based systems where the behavior depends on whether or not the information on the optical disk had been previously accessed.

Abstract: For an optical recordable disk, a heat conductive gold layer can be deposited on a phase-change recordable layer to increase the writing threshold. This higher threshold improves the data stability during readout. However, it has been found that there is substantial inter-diffusion between the phase-change layer and the gold layer. The performance is degraded as a result. A barrier layer between the phase-change layer and the gold layer can effectively prevent diffusion and mixing. Using his barrier, the performance is preserved and the data stability is improved.

Abstract: Antimony-tin alloys including a third element are useful for phase change optical recording. Some preferred alloys have a higher amorphous to crystalline transition temperature and thus, amorphous areas are stable for longer periods. Other preferred alloys exhibit improved CNR or lower noise or other improved performance characteristics.
