High-speed rewritable optical disks based on conventional (eutectic) Sb–Te phase-change materials have low archival life stability and high media noise. We propose Te-free, Sb-based phase-change materials for recording at linear velocities over 28 m/s. These materials combine good optical contrast, rapid crystallization, and high amorphous phase stability. © 2003 American Institute of Physics.

    The stoichiometric Ga4Sb6Te3 and Ga-Sb materials were systemically studied. The alloy Ga4Sb6Te3 shows a fast crystallization speed, very high crystallization temperature, Tx, and high electrical contrast. Although stoichiometric GaSb has similar performance and even faster crystallization speed,...
