Abstract:
PROBLEM TO BE SOLVED: To provide a structural body of a one-side reproduction type combined optical disk which facilitates keeping of spacing and prevents adhesive from protruding into central hole. SOLUTION: The UV-curing type adhesive 16 is interposed between a total reflection film disposed on a data recording area formed on one surface of a plastic disk 1 having the central hole 10 and a translucent film 24 disposed on a data recording area 25 formed on one surface of a plastic disk 2 having the central hole 20 of the same diameter as the diameter of the central hole 10 and thereafter, both disks are adhered and integrated. Annular projecting parts 11, 21 of a prescribed height enclosing the central holes 10, 20 are formed around the central holes 10, 20 on the respective adhesive surface sides of a pair of the plastic disks 1, 2. The annular projecting parts 11, 21 are pressed to each other and the disks are stuck to each other by interposing the UV-curing type adhesive on the outer sides of the annular projecting parts 11, 21.
