Nero Express Glossary 151
Blue Book
This is the standard for CD's that are created in the CD-Extra and CD Enhanced
format.
Bootable CD
Booting means that the operating system is loaded on your computer. Under
normal circumstances, your PC boots from the hard drive. If you need to boot
from something else besides your hard disk for any reason, you can boot from a
floppy disk or CD. Special “bootable CD’s” must be produced to be able to boot
from your CD-ROM/CD-R/RW drive.
Bridge Disc
A CD-ROM which can be read by a normal CD drive as well as by CD-I devices.
It is specified in the White Book. An example of a Bridge Disc is the Photo-CD.
Buffer
Memory built into your CD-Rom or recorder that temporarily stores information.
Buffer Underrun
Buffer underruns are caused when there is an interruption to the flow of data to
the internal buffer of the recorder. This is can be the fault of the software or the
hardware itself. When recording, data is fed continuously to the recorder’s buffer
in order to keep a steady flow of data which is required when recording. When
something interrupts that steady flow, it can cause a buffer underrun and your
disc is no longer useable.
Cache
A fast intermediate or buffer memory which is applied at many different areas in a
computer system. With Nero, cache memory is used to store files in buffer from
drives which cannot be accessed quickly enough in order to ensure that the
writing process continues without interruption.
Caddy
A special plastic housing used to protect the CD. The CD is inserted into the
drive in the caddy.

The acronym for Compact Disc - Digital Audio, this is the first standard for an
audio CD. An audio CD is comprised of several audio tracks whereby generally,
one track corresponds to one song. Each track is additionally sub-divided into
sectors. Music CD’s generally make up this category.
CD-Extra/Enhanced Music CD
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
