Spectral Data Storage Using Rare-Earth-Doped crystals

摘要

Conventional optical data-storage techniques, such as magneto-optic disks and CD-ROMs, record a single bit of in- formation at each particular substrate location. N order to produce the gigabyte- class storage substrates demanded by to- day's computers using such conventional technologies, access to tens of billions of individual materials locations is required. This brute-force approach to optical data Storage has produced impressive results.
