Abstract
Methods and apparatus for applying a bonding layer to a member of an optical recording medium and for bonding together members of an optical recording medium. The methods and apparatus are useful for assembling optical recording media such as compact disks (CDs) and digital versatile disks (DVDs), and are particularly well suited for use with pressure sensitive adhesives. A preferred method of assembling together first and second members of an optical recording medium, wherein each of the members includes an inner surface and an outer surface, wherein at least one of the inner surfaces includes a bonding layer thereon, and wherein at least one of the members includes a data storage surface, includes the steps of: a) curving the first member such that the first member inner surface is convex, wherein the first member inner surface includes an outer annulus, and wherein the outer annulus includes a first portion and a second portion; b) orienting the second member such that the second member inner surface faces the first member inner surface, wherein the second member inner surface includes an outer annulus, and wherein the outer annulus includes a first portion and a second portion;…
