Nero Express Glossary • 109
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 burner. 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 burner 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.
HFS CD
HFS is a file system used by Apple© Macintosh systems. This format is only
suitable for Macintosh discs.
