PURPOSE: To substantially eliminate the influence of adjacent recording parts and to increase the contrast at the time of reading out by forming the element in such a manner that the recording parts are divided by block parts even if org. matter is used.

CONSTITUTION: The recording element 1 consisting of the org. compd. which can be made optically writiable includes a resin and a liquid crystal and the recording parts 2 exist by being segmented by the block parts 3 having the properties (compsn., arrangement, sensitivity, etc.) different from the properties of the recording parts. This recording element 1 includes the resin, the liquid crystal and a photochromic compd. The recording parts 2 are recording units. The recording parts 2 are subjected to recording by lasers but the block parts 3 on the periphery thereof are not recorded by the lasers or are recorded at the level lower than the level of the recording parts 2. The influence of the adjacent recording parts 2 is substantially eliminated in this way and the recording at the high contrast and high density is possible.
