合されている。As this type of information storage medium, for example, one with a sandwich structure as shown in FIG. 1 is known. That is, in the figure, reference numeral 1 denotes a reinforcing plate, and on both side surfaces of this reinforcing plate 1, bases 3, 3 are provided facing each other with a space between them, with spacers 2, 2 interposed therebetween. 3, space parts a and a are formed respectively. A light reflecting film 4 is bonded to the inner surface of each of the substrates 3, 3 as an information forming layer.

うに基盤３。By the way, the reinforcing plate 1 is made of a water-absorbing material such as acrylic, for example, in order to reduce the weight. For this reason, conventionally, in times of high humidity, the reinforcing plate 1 absorbs moisture and deforms, causing the base plate 3 to deform as shown in FIG.
３を精度よく補強することができない不都合があった。There was an inconvenience that 3 could not be reinforced with high accuracy.
本発明は上記事情て着目してな妊れ／こもので、その目

属薄膜からなる情報形成層１５が形成されている。Made of ceramic, etc., the outer diameter is approximately 300 mm, and the inner diameter is approximately 35 mm.
The reinforcing plate 11 is formed with a thickness of about 1 to 2 M, and faces the screen surface of the reinforcing plate 11 with spacers 12 and 13 on the upper white side and the outer side of the V, respectively. The base 14.14 is integrally provided, and the reinforcing plate 11 and the base 14
．． 14, space parts a, a are formed. - The base plate 14 has an inner and outer diameter almost the same as that of the reinforcing plate 12, and is molded from plastic, glass, etc. with a thickness of about 1 to 2 mm, and has Te, A, T, etc. on one side. An information forming layer 15 made of a metal thin film is formed.

の変形は防止されることになる。By forming the lint-retaining film 16 in this way, even if the reinforcing plate 12 is made of a water-absorbing material such as acrylic, the reinforcing plate 11 often absorbs moisture in humid conditions, and its deformation is prevented. This will be prevented.
なお、上記一実施例においては外側のスペーサ１３を固

である。As explained above, since the present invention forms a moisture-resistant protective film on both surfaces of the reinforcing plate, it is possible to prevent the reinforcing plate from absorbing moisture even in high humidity, significantly reducing its deformation, and improving the precision of the base. This has the effect of being able to provide good reinforcement.
