Using Disc Images for Your Master

Have you ever downloaded a program, song or picture from the internet and for some reason it didn't work? Yep, it happens! What would happen if you or I made copies of those bad files? Who would be responsible and who would catch the mistake?

That's why, at dataDisc, our company policy is that you send us a master disc for us to duplicate. You'll be comfortable knowing that everything is going to work the way you want it to work because you've had a chance to test it.

No, it doesn't mean that we can't make exceptions for a super rush job that may only have a file or two. As a general rule, we would make a sample disc and send it to you for approval. So, if you want to take this route, build an extra day or two into your schedule - and a few extra dollars (you'll need to waive your right to approve our master in order to do the rush job of course). It also doesn't mean that we can't accept a "disc image".

What's a "disc image" you say? It is a composite of all the files, tracks and/or video clips that are on your disc all rolled into a single file, often referred to as an ISO file (after the International Standards Organization). It's similar to a ZIP file. Most of today's mastering packages allow you to save off a "disc image". On your CD there is an internal directory that identifies how this large file is to be "decoded" during playback so that you can see, hear or use all the different data that you've placed on the disc. Customers have been successful in sending disc images to us and having any number of discs duplicated from their disc image and you can too. Because we do bit-for-bit copying rather than copying individual files, we can insure perfect copies of your disc.

Bottom line, we want your job to be perfect, no mistakes. Being careful with your data is just one of the ways we can insure that you get what you want, when you want it. If you have a rush, call us. If at all possible, we'll make it happen for you!
