SCSI
Small Computer System Interface. SCSI is a modern bus system to which
different terminal devices such as an SCSI hard drive, streamers or a CD-
recorder may be connected. At this time, SCSI is the only possibility of operating
a CD-recorder on a typically-used computer system.
Sector
A sector is the smallest addressable information unit of a CD. It is composed of
2352 bytes of which - depending on the type of CD used - differing amounts are
available as user data. A sector generally consists of a header, synchronization
bits and user data. It may also have error recognition and correction data. To
read a sector, a drive with simple reading speed requires 1/75th of a second.
Session
When data is written onto a disc, this is called a session. A session is marked at
the start and at the end. You can write onto a disc and complete it in a single
session. If more than one session is recorded on a disc, then this is known as a
multi-session disc.
Session-At-Once
The session-at-once method is mainly used for CD-Extra. With the session-at-
once recording type, a first session with several audio tracks is recorded in one
operation. The latter is then switched off but the CD is not closed (meaning you
are still able to write additional data to it). A second (data) session is then written
and then the disc is closed.
Simulated Recording
Simulation of the burn process in order to test whether there is a constant writing
flow. The procedure is the same as the writing of the disc, with the only difference
being that the laser writer is switched off.
Single Session
When the data/audio is written or recorded to the blank disc one time only.
Super Video CD (SVCD)
Super Video CD or (SVCD) is very similar to a video CD however this format
uses a compression standard called MPEG to store the audio and data. When
creating Super Video CD’s, the source data must be MPEG-2 coded and the
parameters must be suitable for Super Video CD’s. An encoder must be used to
create Super Video CD’s, which must have the required options. As the encoder
supplier whether it supports coding for Super Video CD’s or visit the Nero AG
website at www.nero.com
for additional information on purchasing the encoder.
SVCD discs can be played on DVD players, PC’s with DVD-ROM’s or a CD-ROM
drive with software which allows this type of video format to be seen.
