Abstract :
Two-photon absorption provides a means to record multiple data layers in one disk. Media properties such as non-reflective fluorescent written spots, unnoticeable index change and separated recording and readout absorption spectra make it possible to envision high data capacity disk systems with this approach. Based on experimental evidence we project the data capacity of a 120 mm diameter 10 mm thick disks to exceed 250 GB. By using parallel readout of this type of disk media data rates of Gbit/s should become possible
