Application 10/311,263
disk, placing an upper disk on a different turntable, applying an adhesive
agent in doughnut form onto the upper disk, laminating the upper disk onto
the lower disk, and curing the adhesive agents by irradiation with ultraviolet
light (Br. 2). Appellants state that by using a smaller amount of adhesive
and a smaller radius of the doughnut form on the upper disk as compared to
the lower disk any air bubbles contained in the adhesive will be expelled
therefrom (Br. 2-3). Claim 11 on appeal is reproduced below:
11. A method of laminating optical disks comprising the
steps of:
placing a lower disk single sheet on a turntable;
applying an adhesive agent in doughnut form onto the
lower disk single sheet;
placing an upper disk single sheet on a different
turntable;
applying an adhesive agent in doughnut form onto the
upper disk single sheet, the amount of the adhesive agent applied onto
the upper disk single sheet being smaller than the amount of the
adhesive agent applied onto the lower disk single sheet and the radius
of the doughnut form of the adhesive agent applied onto the upper
disk single sheet being smaller than the radius of the doughnut form of
the adhesive agent applied onto the lower disk single sheet;
laminating the upper disk single sheet onto the lower disk
single sheet in a manner such that the adhesive agent on the upper
disk single sheet and the adhesive agent on the lower disk single sheet
first contact with each other; and
curing the adhesive agents provided on the lower and
upper disk single sheets by irradiation with ultraviolet light rays to
form an integrated, laminated optical disk.
