Several materials including Te, Te:Bi, and Sb2Se3 have been studied for use as a write/read/erase absorbing layer in a capped bilayer or trilayer structure, using Al203 as the phase and capping layers. Discs have been obtained that yield a fully erasable 49dB SNR measured in a 4.2MHz bandwidth and can be recycled at least 500 times. For the materials reported the data retention time is on the order of 4 to 6 hours.
