Buffer Underrun
A buffer underrun is an interruption in the data flow in the internal memory (e.g. of the re-
corder). A buffer underrun results from an interruption in the data flow to the internal buffer.
The buffer continues to deliver data until it is finally empty. When recording, data is fed con-
tinuously to the recorder's buffer in order to keep a steady flow of data. If the steady flow of
data is interrupted, the media becomes unusable. Most modern recorders have a protective
mechanism against buffer underruns.
CD-R
Compact Disc-Recordable is a technology for write-once media. The Orange Book standard
defines the storage of audio data and other computer-readable data.
Image
An image refers to a single file on the hard drive that contains the image for a complete disc.
A disk image can be used to create exact copies on media at a later point in time if problems
occur during the write process or if no recorder is connected to your PC. The image requires
as much free space on the hard drive as the contents of the original disc.
Labelflash
Labelflash is a technology with which pictures and texts can be burned on the label side of a
disc with a laser.
LightScribe
LightScribe is a technology with which pictures or texts can be burned on the label side of
discs with a laser.
Nero Digital
Various MPEG-4 video and audio codecs are collated in Nero Digital and are fully compati-
ble with the standard MPEG-4. Nero AG is continuing to develop these. In this way a sub-
stantially higher quality of the multi-media data is achieved. Further, additional features such
as subtitles have been implemented.
On-the-fly
On-the-fly refers to a method for copying to a disc. The data is transferred directly from the
original storage location to the disc to be burned. To do this, Nero uses a compilation, a
small file that simply refers to the transferred data.
SecurDisc
SecurDisc refers to a security technology that protects data carriers from unauthorized ac-
cess and duplication. SecurDisc can only be burned and password protected with a Se-
curDisc drive. Access with other drives is only possible to a limited extent. The following disc
formats are supported, although without the copy protection feature: DVD+R(W), DVD+-R
DL, DVD-RAM and CD-R(W).
