CD-ROM Labeling Techniques
Abstract
This report provides experimental techniques for CD-ROM labeling. The Naval Air Warfare Center is currently involved in CD-ROM development for the United States military. labeling techniques for Government CD-ROM discs require careful selection and design for the reasons outlined in this report. A CD-ROM disc is manufactured by injecting or pressing a polycarbonate material with microscopic pits in one continuous spiral pattern. A reflective layer of aluminum or gold is then deposited over the polycarbonate. Then a protective layer of material such as DIC-17 is spun across the surface of the metal. And, finally, for product-type CD's, a label is 'Print Screened' onto the finished product. It was found that the quality of CD-ROM discs vary greatly as to the producer's manufacturing process, top-coating protective material, and labeling techniques. Ineffective seal coat material and it's application has been shown to be the 'weak link' in CD-ROM longevity. Disc failure has resulted from penetration of contaminants into the metalized reflective layer. Some manufacturers metalize their discs to the edges thereby not providing a hermetic seal to the environment. Improper silk screen and labeling inks can produce a migration effect into the metalized layer, thereby destroying the disk.
