About optical media, not recorded

cpc code 4754 covers the production and distribution of optical media that is not pre-recorded. This includes blank CDs, DVDs, and other optical discs used for data storage and distribution. The optical media industry plays a crucial role in the broader information technology and entertainment sectors, providing the necessary storage and distribution infrastructure for digital content.

Production process

The production of optical media, not recorded, involves several key steps. First, the base material, typically polycarbonate plastic, is injection molded into the desired disc shape. Next, a thin reflective layer, often made of aluminum or gold, is applied to the disc. This reflective layer is then coated with a protective layer to prevent damage. Finally, the discs are tested for quality and packaged for distribution.

Production inputs

The main inputs required for the production of optical media, not recorded, include polycarbonate plastic resin, metals for the reflective layer, and various chemicals and coatings for the protective layer. Additionally, specialized machinery such as injection molding equipment, sputtering machines, and packaging equipment are necessary for the manufacturing process.

Production outputs

The primary output of the optical media, not recorded industry is blank optical discs that can be used for data storage, backup, and distribution. These discs are often consumed by 4741 Publishing of books, periodicals and other publishing activities, 4742 Publishing of computer games, and 4743 Other software publishing industries, which use them to distribute their digital content.
