【考案の詳細な説明】
本考案は光学方式情報記録円盤（以下円盤とい
う）の改良に関するものである。[Detailed Description of the Invention] The present invention relates to an improvement of an optical information recording disk (hereinafter referred to as a disk).
従来、円盤は塩化ビニル等の樹脂を圧縮成型又
は射出成型にて情報記録成型円盤（以下成型円盤
という）に成型し、該成型円盤全面に真空蒸着、
メツキ法等により例えばAl薄膜の如き金属性反
射膜を形成し、更に反射膜の表面にプラスチツク
樹脂等の保護膜を塗布して形成している。 Conventionally, discs are made by compression molding or injection molding a resin such as vinyl chloride into an information recording molded disc (hereinafter referred to as a molded disc), and the entire surface of the molded disc is vacuum-deposited,
A metallic reflective film such as a thin Al film is formed by a plating method or the like, and a protective film such as a plastic resin is further applied to the surface of the reflective film.
しかしながら斯る円盤においては成型円盤と反
射膜、保護膜と反射膜の接着は樹脂と金属との接
着であるためその接着力は樹脂と樹脂との接着力
より小さく、成型円盤と反射膜、保護膜と反射膜
の接着力の大小によつて反射膜、あるいは保護膜
が容易に剥離する欠点がある。 However, in such a disc, the adhesion between the molded disc and the reflective film, and the protective film and the reflective film is between resin and metal, so the adhesive strength is smaller than the adhesive force between resin and resin, and the adhesive strength between the molded disc and the reflective film, and the protective film and the protective film There is a drawback that the reflective film or the protective film may easily peel off depending on the adhesive strength between the film and the reflective film.
即ち成型円盤と反射膜の接着力が保護膜と反射
膜との接着力より大きい場合は反射膜表面より保
護膜が剥離し、小さい場合は成型円盤表面より反
射膜が剥離する。 That is, if the adhesive force between the molded disc and the reflective film is greater than the adhesive strength between the protective film and the reflective film, the protective film will be peeled off from the surface of the reflective film, and if it is smaller, the reflective film will be peeled off from the surface of the molded disc.
本考案は斯る欠点を除去するために成型円盤の
周縁部で該成型円盤の表面が露出する様に反射膜

る円盤を提供せんとするものである。 In order to eliminate such defects, the present invention forms a reflective film at the periphery of the molded disc so that the surface of the molded disc is exposed, and adheres the molded disc and the reflective film, that is, resin to resin. It is an object of the present invention to provide a disc which can improve strength and prevent peeling between the molded disc, the reflective film, and the protective film.

Alternatively, it is a protective film formed by applying plastic such as vinyl chloride.

の接着が強固に行われる。 The process shown in Fig. 1 is a process of forming a reflective film 2, in which a coating of several tens of microns to several
A mesh-like shielding plate having a mesh size of about 100 μm is inserted and vapor deposition is performed to form a reflective film 2 having pinholes 2a on the peripheral edge of the molded disk 1. When a protective film resin is applied on the reflective film 2, the resin permeates through the pinholes 2a of the reflective film, contacts the molded disk 1, and a dissolution reaction occurs with some organic solvent, alcohol, etc. contained in the resin. The molded disk 1 and the protective film 3 are strongly bonded.

型円盤１と強固に接着が行われる。 The one in Figure 2 shows another embodiment of the present invention. In the process of forming the reflective film 2, a ring-shaped shielding plate is placed to cover the peripheral edge of the molded disc 1, and vapor deposition is performed on the peripheral edge of the molded disc 1. A reflective film 2 is formed so that the reflective film 2 is exposed, and a protective film resin is applied on the reflective film and the peripheral edge portion of the molded disk to form a protective film 3. The protective film surrounds the reflective film 2, and a dissolution reaction similar to that shown in FIG. 1 occurs at the peripheral edge of the molded disc 1, thereby firmly adhering it to the molded disc 1.

く、実用的効果は大である。 As mentioned above, in the disc of the present invention, the molded disc and the protective film are directly bonded at the periphery of the molded disc, and the protective film surrounds the reflective film, so the adhesive effect is greater than that of conventional discs. , there is no peeling phenomenon between the molded disk, the reflective film, and the protective film, and the practical effect is great.
