CD-ROM/ XA

CD- ROM/ Extended Architecture. This CD format makes it possible to store computer data and audio or video data on one track. The different types of data are linked to each other (Interleaving) so that synchronization problems can be reduced.

CD-RW

Compact Disc - ReWritable. A technology for CD-RW (rewritable) media. It is not limited to just one writing, but may be erased and re-written as of ten as desired.

CD-WO

CD - Write Once. As the name implies, it is a CD that may only be written on once. Also refer to CD-R.

Disc At Once

Disc At Once is a method for recording of data onto a CD. With this method, the entire

CD is written in a single process. The CD-recorder first writes a Lead-In, then the data block, and finally a Lead-Out. In contrast to Track At Once, linking blocks are not used between the individual tracks with Disc At Once.

Hybrid Type CD

Image

The term “image” describes all edited data that will later be located on a CD. The creation of an image file is known as premastering.

ISO 9660

ISO Standard 9660 describes the construction of a CD-ROM, so that it may be read and processed by different types of operating systems.

Joliet

This supplement to the standards comes from Microsoft and is supported by Windows

95 and Windows NT. The CDs that are created under this standard are in conformity with

ISO 9660, which allows long file names based on Unicode in additional directory structures.

Mixed Mode-CD

Music and computer data are stored on one CD with this type of CD. The computer data are generally located on track 1 and audio data are located in the ensuing tracks.

Multi-Session-CD

A CD which is written in several sequential sessions is known as a multi-session CD.

On-The-Fly

A process for burning data onto a CD-R. There are two different methods of doing this.

With the classical and older method, all of the data which are to be recorded onto the CD are first stored in a buffer in a large file known as an image file. From there, they are copied or burned onto the CD-R. In contrast to this, the method known as On-The-Fly transfers the data directly from their original memory locations on a hard drive onto the

CD-R.
