Abstract
Multilayer recording in volumetric two-photon absorbing fluorescent Al2O3:C,Mg media is reported. Dynamic random mark-length recording and readout in a single crystalline disk was performed at rotation speed up to 3600 rpm and linear velocity of 14 m/s. Clear eye diagrams were obtained at data clock from 0.32 to 6.5 MHz. Monotones with carrier-to-noise ratio (CNR) from 22 to 45 dB were demonstrated at different data rates.
