CD copiers may be CD-writable (CD-R) or CD-rewritable (CD-RW). In CD-Rs, a laser recorder copies data on a blank CD by selectively burning an organic dye on the CD surface. This process is also known as burning and it is a permanent and irreversible process. CDs burnt by a CD-R can be used only once. But with CD-RW’s, a laser recorder melts an alloy on the surface of the CD in selective degrees. This is a reversible process and these CDs can be used for around a thousand rewrites.
Bulk copying of CDs is required in a lot of cases, such as for handing out CDs to music producers, passing out hundreds of CDs at local concerts, or providing beta versions of a company’s proprietary software. The bulk CD copying process is also very cost efficient. With a tiered price structure, the more the number of units ordered, the more is the saving per individual disk.
Nowadays, with CDs changing in size, a lot of people present their business cards on CDs which not only contains the usual information about them and their company, but also provide a detailed list of the products or services the company offers, along with a whole host of other information. With such use of CDs, bulk copying of CDs for the purpose of using them as business cards becomes absolutely necessary.
