Persistent spectral hole burning permits use of optical frequency for encoding digital information at cryogenic temperatures, with storage densities far beyond the limits of conventional laser–disk recording. In the work presented here, several key technological issues of such a storage system have been investigated. Data were encoded with high spatial and spectral resolution using a specially designed cryostat. The fast tuning characteristics of semiconductor diode lasers were studied to test the feasibility of fast data access in the frequency domain. Fast readout was investigated in a simulation experiment using heterodyne detection with frequency modulated diode lasers.
