。It must be physically stable and capable of recording and reproducing over a long period of time. At present, the recording materials of this method are disclosed in Nikkei Electronics, January 4, 1982, p. 86 and below, "Original disks and memories used for image files" (4). Generally used.T has a low thermal conductivity, a large optical absorption coefficient, and a low separation point, so a recording film with good sensitivity can be obtained, but it is easily oxidized by moisture in the air and optical Since it changes to transparent tellurium dioxide (T e O2), the signal cannot be reproduced, making it very difficult to record news for a long period of time.In other words, it has the disadvantage of a short recording life.
