What is Double Layer DVD – R/RW?

This kind of DVDs come in 12 cm diameter, double sided and has a capacity of 17.1 GB and that is very big. Another one with a lesser size of 8.4 GB comes in 12 cm diameter single sided.

These kinds of DVDs have compatibility issues with Legacy DVD ROMs which are basically of pick up head overrun type. So to avoid this compatibility issue the 2 layers must be equally recorded.

How is Dual Layer recording done?

The dual layer recording standard provides significantly more data to be stored in the disc per side per disc approximately 8.5 GB per side, Compared to 4.7 GB for single layer discs.

A dual layer disc differs from its usual counterpart by inserting a second physical layer within the disc itself. The drive with dual layer capability penetrates through the semi transparent layer. The layer change can cause some time delay but that is very minute.

A few Technical details

• New technology allows material to be either read or recorded on one layer without affecting material on the other layer.

• Storage Capacity: 8.5GB of storage capacity on a single-sided disc — No need to flip the disc

• Largest compatible DVD back-up and data archiving format for computer drives

• Middle zone length can be decided by application/PC in order to shorten finalize time

• The industry’s first Double-Layer DVD-R (DVD-R DL) discs. The new 4x media nearly doubles the storage capacity on DVD recordable discs from 4.7GB to 8.5GB on a single side while maintaining compatibility with existing DVD video players and DVD-ROM drives.

It’s been five years since I entered the CD and DVD duplication industry and though I was making a lot of money at first, the ever-evolving technologies didn’t like me getting richer everyday. The big-time orders are still there and I have no complaints regarding them, but the money I was making through smaller quantities of CD or DVD duplication received a major setback.

Well, Technology; I’ve no grudges against your advancements, but why do you have to let people know about your availability? Today, the biggest consideration one makes regarding getting a small number of CD-s or DVD-s written is whether they should do it themselves or shall they come to me; in the days of yore, there was but one option – allow me to burn your discs as well as your pockets. But things have changed and CD or DVD duplication is no more burning a disc and marking it with a sharpie. It makes the job look incomplete as well.

• The Pros of outsourcing:

• Customized direct-disc, professional quality printing.

• A guarantee against money loss; if a media turns out bad, it’s the responsibility of the person who agreed to do the mass-duplication to replace the same.

• No blockage of money regarding CD duplication systems and no maintenance cost involved.

• No need to appoint a person to handle the job.

• If a DVD or CD duplication equipment fails, the only solution remains is to outsource the job. That’s hyping the investments up plus a lot of repair-related tensions as well as costs. That also makes a person lose on the deadlines.

• In case the quality turns out bad, you need to re-invest the amount to make your client happy whereas if you would have outsourced, your profit margins would have been your desired one.

• Post-duplication works (printing, assembly, insertion, and shrink-wrapping) require special equipment; it’s a bad investment to go for them unless a steady revenue can be earned through them.

Folks, please don’t be penny-wise and pound-foolish; a try to save a little amount may get the larger amounts flowing down the drain and when we mean CD or DVD duplication, we also take into account the printing and packaging parts. You can’t get that done only from us, if you are planning to burn your own things.
