Q A

How much information can I fit on one CD?

The type of disc and software you use greatly affect the amount of data you can fit on a disc.

A DVD+RW disc can hold approximately 4.7 GB of data or up to 3 hours of video depending on the video-quality setting you choose when you record the disc.

When you use HP DLA, a DVD+RW disc can hold approximately 4.6 GB of information.

A single session CD written with HP RecordNow can hold 650 MB of data or 74 minutes of music (an 80 minute CD will hold 700 MB or 80 minutes of music).

Most of the time you will probably be writing multisession CDs. Multisession allows a CD to be recorded, removed, and read on a CD-ROM drive and then have more information added later. Each time you record a session, overhead is added to your data; about 23 MB of overhead for the first session and 14 MB of overhead for each session after that. Therefore, the total amount of data that you can fit on the CD varies depending on how many sessions are written and how much data is in each session. So when planning your work, try to write as much data in a session as you can.

When you use HP DLA with a CD-Recordable (CD-R) disc you can store up to approximately 618 MB of data on 74-minute media or 670 MB on 80-minute CD-R media.

When you use HP DLA with a CD-ReWritable (CD-RW) disc, the amount of data that can fit on the CD is about 530 MB because of the additional file structure overhead.

Q A

Can I do other things while my CD is recording?

If your new drive is a cd12, cd16, cd24 or dvd100i, it has Buffer Underrun Protection Technology that eliminates buffer underrun errors. You can use your computer to do other tasks while you write discs. You never have to turn on your drive's buffer underrun protection technology because it works automatically in conjunction with your drive's mastering software.

HP MyDVD Video by Sonic does not capture video efficiently when your computer is performing other tasks. Your DVD disc will not be ruined, however video capture performance may be affected or there may be errors on the disc that require you to perform the recording operation again.

If your drive does NOT have buffer underrun protection technology you can do other things on your computer when using HP DLA; however, when using HP RecordNow, there won't be much computing power left to run other programs. Trying to run other programs at the same time can interrupt the recording process and corrupt the disc because HP RecordNow and other mastering applications need a constant stream of data to write to the disc.

So, before you start a recording session with these programs do the following:

●Sign off from email.

●Log off of the network.

●Turn off any other programs that might interrupt, such as a calendar with a reminder feature or a scheduled backup that might begin.
