Extended write pulse compensation for 100GB rewritable triple-layer disc

Abstract

In multi-layer rewritable optical disc, we introduced extended write pulse compensation, which controlled laser pulse according to combination of both preceding and successive space lengths of 2T-mark. By applying this write strategy, rewritable triple-layer disc with a capacity of 100GB was realized with BD optical systems. In particular, the effect of this write strategy was significant in transparent information layer.
