CD Duplication Explained

It took some 20 years before CD duplication methods became efficient and cost-effective. From a single CD to thousands, better tools and devices have made it possible for anyone to duplicate CDs even in the comforts of their own homes. The end products are not too shabby, either. CDs duplicated using modern software and hardware can boast of top quality and reliability.

Years ago, CDs came mainly as readable discs but as more and more consumers began clamoring for the kind of quality usually only available in digital recordings, manufacturers began producing CDs that could be encoded easily. Called CD-Rs or CD-Recordable discs, these discs made it possible for anyone who can operate a computer to perform CD duplications.

What CD duplication means

CD duplication is, put simply, photocopying, since light (laser) is being used to produce a duplicate. Imagine taking a master disc and making copies of it in a short time. What you have is a number of CDs which are exact replicas of the master, containing the exact files and data that the master disc has.

What you need

For starters, you will need a reliable computer, a CD-writer or burner and a music- or data-management software. Depending on what kind of files you will be copying, you can choose 'data CD' or 'music CD'. Most softwares will also allow you to choose which speed you want to use to burn the CD with. While faster speeds allow you to produce duplicates within a short time, slower speeds are less likely to produce errors.

What a CD burner does

A CD burner essentially functions as a photocopier. It is either a device that's already built in to the PC or an external writable drive. These days, desktop and notebook computers already come with CD drives or burners as standards. Even music enthusiasts are hooking a separate CD burner to their audio and stereo systems to facilitate faster duplication.

The CD burner uses a moving laser much like a regular CD player, except that it not only has a 'read laser', it also has a 'write laser'. The write laser interacts differently with the blank disc by producing a stronger light to change the disc's surface and thus alter it.

How CD duplication is done

When people say they 'burn' CDs, they mean copying data from a master source – a hard disc, a floppy disc or another CD – to a blank CD. A blank CD is either a CD-R or a CD-RW or re-writable. A CD-R will allow you to copy data on it but not change it. Whatever data you have on the disc will remain unchanged; you cannot make modifications nor delete anything. With a CD-RW, however, you can erase data and copy over and over again.

A blank CD has a flat, smooth surface, made of a reflective metal layer. Another layer underneath this reflective metal is made of photosensitive dye. This dye is translucent when the CD is not yet encoded. But when the CD-writer begins to 'burn' data onto the disc, the dye later is heated using a particular frequency. This is where the dye layer turns opaque and this time, will not allow light to pass through.

What the blank CD now has is no longer a smooth, flat surface but a surface that has microscopically darker areas which contain a digital pattern 'burned' into them. The altered surface now contains data copied from the master source.

Speed matters

The rate at which CDs are duplicated will depend greatly on several things: the amount of data on the disc, the speed of the copy disc, the speed of the connection between your PC and CD burner and the speed of the CD burner itself. At a 1x speed for example, the disc will spin at the same rate it does when you put it in a CD player. So if you have a CD that contains 120 minutes of recording, you will be able to duplicate that CD in 120 minutes as well.

Or to record all your favorite love songs and distribute DVDs as your wedding giveaways? DVD duplication is the answer to your quest for a cheaper and unique give-away either for weddings, baptismal, birthdays, or any other memorable occasion.

DVD duplication is the act of reproducing optical media through copying. It generally means producing discs in small quantities. The content of the DVD disc is duplicated on an existing recordable DVD.

Duplication is the process in which small quantities of DVDs are manufactured. DVD media is loaded onto burners. The information is extracted through digital means from the master source which are then transferred to a blank disc. The information is then verified and the disc either accepts or rejects the copied version. With the advent and popular use of cheaper media, it is now possible to offer the same level of DVD duplication services to either customers who need small quantities or for those who opt for larger quantities.

DVD duplication has both cost and quality advantages. Using a DVD duplicator is proven to be a fast, cheap, and convenient method to get products to its intended market. If your business involves producing music and video products, you need to reach your intended market quickly and effectively. It is wise then to purchase a DVD duplication machine.

On the other hand, replication is the standard used when making large numbers of copied discs. A glass master of the information stored on the disc is made that, in turn, produces stampers. The stampers are used for injection molding of the information onto the disc. Layers of polycarbonate plastic protect the information which is then lacquered, screened, and ultimately packaged. Since most of these processes are fully automated, the cost per unit is cheaper when orders are from one thousand to two thousand pieces.

So there, start making copies of your favorite video or audio file and regale your family and friends with your taste in movies and music.
