摘要：in a reversible memory system, a pulsed laser beam generated from a laser unitis directed to a recording layer (2) formed on a substrate 1. The recording layer (2)essentially consists of a recording medium, for example, an iron-nickel alloy containingiron as a mayor component and 27 to 30 atomic % of nickel, which undergoes martensitetransformation from a low-temperature phase (D) to a high-temperature phase (E) at apredetermined temperature Af and which undergoes a stress-induced transformation (a)at a characteristic temperature Md. When a region of the recording layer is irradiatedwith the laser beam having a predetermined intensity, the region undergoes a stress-induced transformation (a) so that the region is changed from the high temperaturephase (A) to the low temperature phase (8).
