Abstract

Recording and readout in two-photon absorbing Al₂O₃:C,Mg optical data storage media was investigated for crystals having different concentrations of color centers and for two orientations of the crystal optical c-axis. The writing and reading efficiency of the media was increased by taking into account the anisotropy of optical absorption and by rotating the laser light polarization vector synchronously with the disk rotation. The parameters for writing and non-destructive reading of the bits in the volume of a single crystal disk are reported.
