Abstract

PURPOSE:To increase the speed of initialization as well as recording and erasing and to heighten a recording level so that recorded information is stabilized by forming a recording layer of a compsn. consisting of an InSb intermetallic compd. in which In or Sb is partly substd. with a specific element expressed by M. CONSTITUTION:This recording medium has a substrate 11 and the recording layer 13 which is reversibly changed in phase between different crystal phases when a light beam is projected thereto. The recording layer 13 is characterized by having the compsn. consisting of the InSb intermetallic compd. in which In or Sb is partly substd. by the element expressed by M and in which M is at least one kind of the elements selected from Ag, Pt, Pd, Ni, and Si. The recording layer 13 is preferably made of the alloy expressed by the formula In50-xSb50Mx (x is 0<x<20) or In50Sb50-xMx (x is 0<x<15). The information recording medium which allows the execution of the initialization and erasing at a high speed, obviates the generation of defective initialization and incomplete erasing and has the high stability of the recording and the high recording level is thereby obtd.
