Paper Abstract

Thermal deformation is calculated to clarify the cause of material flow due to multiple overwriting in a phase-change optical disk. The results suggest that the molten material of the recording layer moves along the recording track by thermal deformation of layers. Moreover, the direction of the material flow depends on the Al reflective layer thickness.
