TASCAM CD-RW900 71 − IntroductionIn this maanual, we use the term “recordable” disc todescribe a CD-R or CD-RW disc that has not beenfinalized, i.e. further recording is possible on the disc.“Recordable” discsAlthough audio data may be written on a CD-R or CD-RW disc, a standard CD player will not be able to readthe data (i.e. play back the audio) until a final *TOC hasbeen written at the start of the disc.*TOC=Table of contents:information of recorded data, which contains titles, startingand ending addresses, and etc..The process of writing this table of contents is knownas “finalizing”. Once this has been done, no further datacan be written to the disc. See “Finalizing” on page 25for details.FinalizingIn the case of a CD-RW disc which has been finalized,the whole of the disc may be erased, or the disc maybe “refreshed”, and the disc re-used.In addition, a CD-RW disc that has been finalizedmay be “unfinalized”, i.e. only the TOC is removed.This allows further tracks to be recorded to the disc,provided that there is space on the disc.About CD-R and CD-RW discsCD-R discs can be recorded once only. Once they havebeen used for recording, they cannot be erased or re-recorded. However, if space is available on the disc,additional material can be recorded. The pack-aging ofCD-R discs will include one of the following logos:By contrast, a CD-RW disc can be used in much thesame way as a CD-R disc, but the last track or tracksrecorded can be erased before the disc has been“finalized”, and the space on the disc can be re- usedfor other recordings. The packaging of CD-RW discswill include the logo one of the following logos:H o w e v e r, y o u s h o u l d n o t e t h a t a n a u d i o C Dcreated using a CD-RW900 disc may not play backsatisfactorily on every audio CD player. It will, naturally,be playable on the CD-RW900. This is in no way alimitation of the CD-RW900 itself, but of the differencebetween the different types of media and the methodsused to read them.There are precautions that you should take whenhandling CD-R and CD-RW discs.≠ Avoid touching the recording (non-label) side of adisc on which you will be recording. Recording ona disc requires a cleaner surface than playing back,and fingerprints, grease, etc. can cause errors in therecording process.High Speed≠ CD-R and CD-RW discs are sensitive to the effectsof heat and ultraviolet rays. It is important that theyare not stored in a location where direct sunlightwill fall on them, and which is away from sources ofheat such as radiators or heat-generating electricaldevices.≠ Always store CD-R and CD-RW discs in their casesto avoid dirt and dust accumulating on their surfaces.≠ When labeling CD-R and CD-RW discs, always use asoft oil-based felt-tipped pen to write the information.Never use a ball-point or hard-tipped pen, as thismay cause damage to the recorded side.≠ Always keep the recording sides of the discs awayfrom grime and dust to avoid a reduction in soundquality. To clean a disc, wipe gently with a soft drycloth from the center towards the outside edge. Donot use thinner, gasoline, benzene or LP cleaningfluid, as these will damage the disc and cause thedisc unplayable.≠ Do not put labels or protective sheets on the discsand do not use any protective coating spray.≠ If you are in any doubt as to the care and handling ofa CD-R disc, read the precautions supplied with thedisc, or contact the disc manufacturer directly.
