Abstract (en)

[origin: WO0031734A1] A magnetic disk has a layered configuration comprising a recordable layer (110) and a reflective layer (112). Laser-stimulated recording takes place by a magnetic head (102) that obstructs the laser beam for a minor portion. The converging laser beam traverses the recording layer and gets reflected at the reflective layer, whereupon it reaches its focus in the recordable layer. The head gets only a fraction of the radiation. This enables to keep the head's temperature well within control.
