Mixed Mode CDs
A CD which contains both computer data and audio data is known as a Mixed
Mode CD. The computer data is stored on the first track. All the other tracks
contain audio data. Modern CD players do not reproduce the first track. Older
models, however, will try to "play back" the computer data which, in some
cases, can cause damage to the stereo system.
Multisession
A data CD can be written in several sessions. This must be set accordingly while
writing. Typical instances where multisession CDs are used are regular backups
and Photo CDs which are gradually filled up.
Multitasking
Windows allows you to open several windows simultaneously. This is known as
multitasking. When writing CDs, only the writing software window should be
open (running), for full and exclusive use of the computer's resources. Screen
savers, modems and network functions should be deactivated as they all use up
computer resources which, in extreme cases, may disrupt the writing process.
On-the-Fly
Writing directly onto a CD-R without creating a physical image. If it is not possible
to gain fast access to the source files, the writing process cannot be carried out
successfully ("Buffer Underrun"). Only small amounts of data with simple data
structure should be written On-the-Fly. The source files should be copied onto
the hard disk.
Orange Book
The Orange Book contains the specifications for CD-R (recordable CDs). These
CDs contain no information other than some special data (ATIP Codes), and
they can be written according to any of the other color book standards.
Manufacturers of blank CDs have to abide by the regulations in the Orange
Book.
Packet Writing
A method of writing CDs which makes it possible to write data in smaller blocks
(packets) than is the case with the usual Track-at-Once or Disc-at-Once procedures.
This procedure allows data blocks to be written onto the CD-R without having
to finish the particular track. A further advantage of Packet Writing is the simple
updating of existing files. Data can be simply added without having to rewrite
the file directory each time.
