Abstract

An ETT ('eight-to-ten') method has been proposed for two-dimensional spatial encoding of information stored in two- or three-dimensional, in particular fluorescent optical carriers. The method specifically ensures the same writing density as DVD carriers with EFM ('eight-fourteen modulation') modulation code but for a 0.8 x 0.4 ∩ information pit (fluorescent mark), i.e. as in CD data carriers. The larger pit size enables a simpler technology for manufacturing fluorescent multilayer carriers, for instance of ROM type, and a stronger fluorescent signal in reading. The high writing density is ensured through virtually 100% filling of the information layer area with fluorescent marks in a gap-free manner. This allows application of the parallel data reading procedure and a ten-fold higher reading speed than in DVD systems and increasing the size of the channel bit to 0.4 νm - which is 1.5 and 3 times higher than for CD and DVD formats.
