Abstract

PURPOSE:To avoid influence from outside, increase humidity proof and chemical proof properties and heighten durability by sealing the hologram of a covered hologram disk in a protecting space. CONSTITUTION:A cover member 11 is provided on the hologram disk 10 through spacers 12, 13. Chamfered parts 10a, 10a', 11a, 11a' are formed on the common open end of an outer periphery and an inner periphery of the hologram disk 10 and cover member 11. After providing donutlike spacers 12, 13, these parts are filled with an adhesive 14, and the disk 10 and cover member 11 are joined in one body. As the hologram H0 is thinner than spacers 12, 13, it becomes positioned in a sealed protecting space 15 enclosed by the spacers 12, 13 and cover member 11 to form a covered hologram disk 16. Flat, wide spacers 12, 13 are used as far as possible.

。As shown in Fig. 1, in the hologram disk 1, holograms H9 are recorded on a disk-shaped glass plate 1a at equal angles on an arbitrary circumference. When this hologram disk 1 is mounted on a 10j unit 2 shown in 3-1 and rotated, and a laser beam Lb is projected onto the hologram Ho, a diffracted beam L1 is emitted. If the hologram Ho is set to ai''θ in a special manner, the diffracted light L1 will oscillate left and right, and this phenomenon can be utilized as a laser scanner.

）が形成されている。The cover member 11 is stacked on the side of the hologram disk JO on which the hologram Ho is formed to constitute a guarantee cover. On the other hand, if the cover member 11 directly contacts the hologram Ho, the hologram will be pinched, so to prevent this, a spacer (described later) is interposed between the hologram disk 10 and the cover member 11. This spacer is for the purpose of preventing damage caused by the 1st hologram Y4
It has a chivalry function as a pillar and a sealing function that shields and seals the hologram from humid outside air. or,
In order to improve the adhesion between the hologram disk 10 and the cover member 11 and to facilitate the adhesive filling operation, the common open end surfaces of the outer and inner peripheries of the hologram disk 10 and the cover member 11 are designated by the reference numerals. ]Oa, ]0'a, a chamfered portion is formed as shown by the symbol 11a, llk, and furthermore, from the requirement of 1;

A donut-shaped spacer (not shown) is interposed on the outside of the hologram Ho, and a donut-shaped spacer (13) is interposed inside the hologram Ho.Spacers = 12 and '13- have the same size. The adhesive 14 is filled in one step of the filling space (11), and
The hologram disk 10 and the cover member 11 are integrally joined, and the hologram I (o) is positioned between the spacers 1 and 15 surrounded by the spacers 12 and 13 and the cover member 11. Then, a cover-covered hologram disk 16 is produced.
