Burning and Stamping Compact Discs

There are two methods one could use to obtain production run copies of a Compact Disc, duplication and replication. From an end-user perspective, there is certainly hardly any difference between both. Both methods can handle creating excellent digital sound (or video, or programs, etc.) but to a computer, the products vary.

The Replication Process

To begin manufacturing Compact Discs from scratch, a digitized sample from the information to become printed on each CD must be meticulously scrutinized for almost any data corruption. Once the data is verified, a glass master is produced. The quality in the glass master may be the true indicator of how well a final product will turn out. From the glass master, a stamper is created utilized to create new CDs.

For each new help in the manufacturing process, the truth and precision in the bandwidth are monitored very closely so that you can be sure that every disc is a great clone of the original. After molding, the disc turns into a micro-thin aluminum layer to reflect the laser in the player to the equipment, plus a layer of lacquer to shield the data before being printed or labeled with the information contents. Once the verification process is complete, the disc is on packaging and shipping.

The Duplication Method

You have probably duplicated all or part of a CD, however, it is more often known as “burning” a CD. The process is similar in industrial applications, except on a far more massive scale. Instead of your single drive in a single tower, a production duplication facility has a huge selection of towers-each with plenty of burning drives- linked together to make hundreds of copies at a time. After the data is verified from the Master Data, the operation is over.

Replication Advantages and Disadvantages

For one the most part, replicating discs could be the cheaper method when manufacturing a sizable quantity of CDs. There are also more labeling options if you select the replication method. Replication is right for high volume runs, and several facilities are equipped to automatically assemble the finished discs into jewel cases or sleeves. The lead time is a little longer on production machines, however, so with moderately sized orders you may expect it to adopt weekly or so for the ultimate product to become delivered while it might take just a couple of days while using the duplication process. Most companies will require no less than 1,000 discs or maybe more per order.

Pros/Cons of Duplication

On the upside, duplication runs usually don’t take greater than 2 or 3 days even for a run-up to five,000 units. Printing your individual labels can be a big cost-saver over prepress charges that a replicator might charge. However, the charge for each and every disc is slightly higher, and also the small run nature of all of people facilities makes packaging the media a hand assembly process, which can be costlier for your same service a replicator provides. Additionally, CD-Rs employed for duplication are vulnerable to sunlight that may potentially create a CD unreadably.

Is There Any Real Difference?

The technique of duplication always involves a CD-R or CD-RW, while replication brings about the CD-ROM or CD-Audio. Duplication is exactly what one does when he copies one disc to a new disc having a computer. The information or information is sequentially ‘burned’ towards the disc. Replication is reminiscent of the output of vinyl records which involves a stamper that adds your data for the disc by stamping.

CD Duplication and Replication results are very similar. Because they extract the main information the same way, the conclusion products perform very similarly. The main visual difference comes in the label, whether they are printed or screened in. The real difference will be the need that this client has: for large runs that aren’t rushed, replication is just about the best bet, but if you may need the discs quickly or have fewer discs duplication may be the strategy to use.
