らず、又消去しようとしても極めて内錐であった。In conventional information media of this kind, the surface of the concave-convex pattern is covered with a heat-resistant film for protection;
(There is no consideration given to erasing the concave-convex pattern Y of a desired portion for the purpose of partially erasing recorded information, and even if an attempt was made to erase it, it would be extremely inconvenient.

This value is higher than the softening temperature of 3). Therefore, the heating element (5)
The auxiliary layer immediately below is softened, and the concave portions of the concavo-convex pattern immediately below it are filled with the softened auxiliary layer (3) as shown in FIG. 6 (:), and the concave-convex pattern becomes flat and erased.
