Introduction 2.4. Type of Writing Disc-At-Once When only a single recording session (lead in/data/lead out) is to be recorded onto a disk, itis called “Disc-At-Once”. When using Disc-At-Once, no additional data can be recorded onto the disc, even if there is available capacity. The advantage of this method recording is that it enables creation of discs that can be played back on almost any CD player or CD-ROM drive, because there are no links inserted between the data tracks. Track-At-Once When many sessions are to be recorded onto a disc, itis called ‘Track-At-Once”. Ifthere is space available on the disc, additional data can be recorded onto it. The advantages of this method include being able to record additional sessions onto à disc, and using a CD-ROM of backup data. (Refer to “Multisession".) Session-At-Once A "Session-at-Once" recording almost corresponds to a "Disc-at-Once recording", i.e. all data ("Lead-in", data area and "Lead-out" are written in one go The only difference is that the CD is not ‘finished”, Le. after a "Session-atOnce" recording you still have the possibility to write à further "Session" on the CD at a later date Multi-session The recording of lead-in/data/lead-out is referred to as one session. The Disc-At-Once method is also referred to as “Single Session”, because the disc is only recorded once. A disc that has had multiple additional session recorded onto it using the Track-At-Once method is called “Multisession”. Packet Write The Packet Write recording method was developed. It differs from Track-AtOnce or Disc-AtOnce in that data is recorded in small fixed sectors of 64k bytes, known as packets. The advantages of this method are elimination in overhead per session and the elimination of buffer under run errors. This method, however, cannot be utilized for audio data. À number of formats, such as UDF and CD-R FS, can be used when recording using the Packet Write method.

Specification English Appendix A. Glossary CD-DA Compact Disc - Digital Audio. The typical music CD is written with this CD format. At this time, up to 74 minutes of music can be written on a CD. The corresponding standard is the Red Book. CD4 Compact Disc - Interactive. This format allows the storage of different types of data such as images, music or video on a CD. The process is defined in the Green Book. CD-R Compact Disc - Recordable. A technology for CD-R (recordable) media. Also refer to CD-WO, Compact Disc - Write Once, limited to just one writing. CD-ROM Compact Disc - Read Only Memory. This is described in the Yellow Book. Differing types of data that can be read by a computer such as programs, text, image data or sound may be stored with this CD format. CD-ROM - Mode 1 and Mode 2 À supplement to the CD-ROM format which provides an additional error recognition and correction function. Mode 1 is especially used for computer data and employs a code for error correction. Mode 2 is used with CD-ROM/ XA and CD-I with audio data and contains an error recognition code only. 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 often 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 AtOnce 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 AtOnce. —E-15—

Specification Enhanced Music CD, CD + and CD Extra An expansion of Audio or Mixed-Mode CD consists of two sessions. The first session corresponds to CD-DA, while the second session consists of computer data. The process is specified in the Blue Book Finalization Finalization is the permanent closing of the writing procedure on a CD. After that, it cannot be written to, regardless of whether it was produced as a single-session or a multi-session CD. Green Book A book of CD Interactive (CD-I) standards published by Philips and Sony in 1986 High Sierra The forerunner of today's ISO Standard 9660. it was published in 1986. With the passage of time it has lost its significance. Hybrid Type CD A CD-ROM disc storing "two different platforms of softwares" for Windows and Macintosh etc. 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 À 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 à 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 CDR. -—E-16—
