The present state of technologies for rewritable optical data storage is reviewed. The potentials and pitfalls of the existing technologies are described. Rewritable optical data storage is based on magneto-optical (MO) and phase-change (PC) media technologies. Both the technologies use a focused laser beam to raise the temperature of the medium beyond a certain critical temperature for writing, erasure, and overwriting of data. The storage density of the media, achievable data rates during recording and readout, longevity, reliability, and cost of finished products are some of the factors that characterize the performance of these data storage systems.
