Nero Express Glossary 154
DVD+R/RW
A rewritable and non-rewritable format developed in cooperation by Hewlett-
Packard, Mitsubishi Chemical, Philips, Ricoh, Sony and Yamaha. It is a rewritable
format that provides full, non-cartridge, compatibility with existing DVD-Video
players and DVD-ROM drives for both real-time video recording and random data
recording for many PC and entertainment software applications.
EDC/ ECC
Error Detection Code/ Error Correction Code. This process serves for the
recognition and correction of scan errors which might be caused on the CD
surface by scratches or dirt.
Enhanced MusicCD/CD-Extra
CD Extra is the latest standard for audio CD’s and with a multi-media component.
A disc in this format always has two sessions. The first session only contains
pure audio data which can be played on an audio CD player while the second
session contains computer data in any format. This format puts audio AND data
on the same CD. The audio is recorded first with the data recorded in a second
session.
Fast Copy
With the fast copy method, Nero reads the data directly from your CD-ROM/DVD
drive and writes it directly onto the target disc in your CD recorder. This method is
faster than copying an image file and it does not require an approx. 100MB of
space on your hard disk. The disadvantage of this method is that a “buffer
underrun” can occur. A buffer underrun always occurs if the CD recorder writes
faster than the data can be sent. The reasons for this can be a source which is
too slow (either hard disk or CD-ROM/DVD drive) or the hard disk is too
fragmented and the data flow is slowed down due to the excessive number of
accessed operations. This means that the data on your hard drive is scattered
into many parts of the drive and the CD-ROM/DVD drive needs time to look for all
the pieces and put them together.
Finalization
Finalization is the permanent closing of the writing procedure on a CD. After that,
it cannot be written to, regardless of whether it was produced as a single-session
or a multi-session CD.
Frame
A sector is made up of 98 frames. A frame contains 24 data bytes and 9 control
bytes. With an Audio-CD, 75 sectors provide one second of played music.
Green Book
This is the standard for CD's that are created in the CD-I format.
