Present limits of data storage using dye molecules in solid matrices

Optical data storage offers the potential advantages of high storage densities, fewer mechanical problems, low reading and writing energies, ruggedness, and higher data rates. Currently, the only true photonic optical storage medium is the spectral hole burning scheme. The features of the technique are presented, the materials (e.g. see figure) and necessary laser technology presented, and a view is given of the prospects and requirements for future commercial development. magnified image
