1 − IntroductionTASCAM CD-RW901 In this manual, 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” discsAbout CD-R and CD-RW discsCD-R discs can be recorded once only. Once theyhave been used for recording, they cannot be erased orre-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 “final-ized”, and the space on the disc can be re- used forother recordings. The packaging of CD-RW discs willinclude the logo one of the following logos:High SpeedHowever, you should note that an audio CD createdusing a CD-RW901 disc may not play back satisfactori-ly on every audio CD player. It will, naturally, be play-able on the CD-RW901. This is in no way a limitationof the CD-RW901 itself, but of the difference betweenthe different types of media and the methods used toread them.There are precautions that you should take when han-dling 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.•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 sunlight willfall on them, and which is away from sources of heatsuch as radiators or heat-generating electrical devic-es.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 usea soft oil-based felt-tipped pen to write the informa-tion. Never use a ball-point or hard-tipped pen, asthis may 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 and CD-RW discs, read the precautions sup-plied with the disc, or contact the disc manufacturerdirectly.••••••About finalizingAlthough audio data may be written on a CD-R orCD-RW disc, a standard CD player will not be ableto read the data (i.e. play back the audio) until a final*TOC has been written at the start of the disc.*TOC:Table of contentsInformation 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 furtherdata can be written to the disc. See “Finalizing” onpage 31 for details. In the case of a CD-RW disc whichhas been finalized, the whole of the disc may be erased,or the disc may be “refreshed”, and the disc re-used.In addition, a CD-RW disc that has been finalized maybe “unfinalized”, i.e. only the TOC is removed. Thisallows further tracks to be recorded to the disc, provid-ed that there is space on the disc.
