摘要:
Double sided optical memory disks are produced by dropping a viscous adhesive material hardenable by ultraviolet radiation at predetermined longitudinal intervals onto an elongated cloth material of uniform thickness thereby causing the adhesive material to become absorbed by and contained in the cloth material, thereafter placing this cloth material sandwichedly between two optical disk pieces each containing a recording layer, thereafter applying pressure between these pieces such that the sandwiching pieces remain separated uniformly by a predetermined separation distance, and thereafter applying ultraviolet radiation to and thereby hardening the adhesive material while the disk pieces are maintained at the uniform separation distance.
