The process of manufacturing CDs and DVDs has changed the way in which the world looks at and listens to entertainment. Prior to the introduction of CD\/DVD mass-production, less sophisticated means, such as vinyl records, tapes and VHS were used to mass-produce music and movies. But now, with the revolution of CD and DVD manufacturing, we take a step up. Music and movie fans no longer have to purchase bulky records or poorly manufactured tapes in order to listen to music or enjoy their favorite movies. With the birth of the compact disc, anyone can easily slip this small, shiny circle into their car stereo or home entertainment center for their listening and\/or viewing pleasure. But how did the mass-production of CDs and DVDs become such a powerful force in the world? What was the indispensable step that made the manufacturing of CDs and DVDs possible, and in the process shaped a new mold for the way the world enjoys its entertainment? <\/p>\n

For the people who would like to learn the answers to these questions, it must first be understood that the process of manufacturing CDs and DVDs is complicated. Remarkable chemical processes combined with complex and time-consuming procedures are the ingredients that go into the formation of a disc. In examining the rise of CD\/DVD technology, it is crucial to understand the process of replication. When manufacturing discs, many steps take place: glass mastering, photoresist or non-photoresist mastering, post mastering, and electroforming. The most vital step, however, in the manufacturing process is replication.<\/p>\n

Replication of CDs and DVDs is the step that takes place after the quality of the glass master has been determined to be ready for large-scale production. This is the critical point in the manufacturing process. It is the point in which the album creates a super-star out of a singer. CD and DVD replication has made it possible for listeners from Tokyo to New York and everywhere in between to have access to the same discs. It is a process that has truly revolutionized the fashion in which the world listens to music and sees movies.<\/p>\n

What exactly goes into the replication process? It involves a few steps, each of which must be understood to learn how replication works. Replication begins in a factory with a CD molding machine. This machine uses exceedingly high-temperature polycarbonate injectors. Hot molten plastic is inserted into the mold cavities forming a disc. Each molding can produce 900 discs per hour! Cool water is then run so that it gathers around the molding, solidifying the plastic and the molding is then opened. This entire process takes just three to five seconds.<\/p>\n

Next, after molding, a vacuum handler moves the disc onto a cooling station. The disc now contains all of its digital information at this point, but does not yet have the reflective layer that makes the disc playable. Then the disc passes into a chamber to undergo a process called “sputtering”. During the sputtering process, metal is coated onto the data side of the disc; the side not containing the record label.<\/p>\n

Next, lacquer is coated onto the metal layer providing a surface for printing the DVD or record label. The printing ink must be compatible with the lacquer. If not, the disc may fracture and become ruined. This is also true for CD and DVD owners<\/a>. Pens used to write<\/a> on discs must be compatible for the same reason. This completes the replication process.<\/p>\n

Replication has been instrumental in the mass-production of CDs and DVDs. It has altered the way we listen to and view entertainment. The next time you head down to the record store to buy that hot new CD or the latest DVD release, take a moment to think about the replication process. It has truly allowed CD\/DVD manufacturing to be driving force in the world of entertainment.<\/p>\n
