Parallel readout of multi-layer optical disks recorded with a blue laser

Research output: Contribution to journalConference article

Abstract

Application of two-photon absorption for recording multiple data layers in one disk was discussed. During recording by two-photon absorption, the recorded bits fluoresce when excited by a suitable readout laser beam. The recorded area of these disks enables optical beams to access the volume of the disk without significant aberrations and losses. The total disk capacity for a two-photon recorded fluorescence disk is determined by the total number of data layers recorded in one disk and the areal data density in each data layer. Media properties such as non-reflective fluorescent written spots, unnoticeable index change, and separated recording and readout absorption spectra increase the capacity of storage systems.
