Abstract
In erasable optical storage, the requirements for writing, read and erasure processes to the distribution of the optical field and the time-space distribution of the temperature field induced by pulse laser are harsher than those in nonerasable optical storage. So, it is highly necessary to consider about parameters in optics, thermology and structure, latent heat effect (phase-change model), magneto-optic Kerr and Faraday effects (magneto-optic model), etc. more carefully and all-sidedly in designing the distributions of optical field and heat field.
