TDK CORPORATION MITSUBISHI CHEMICAL CORPORATION RICOH CO., LTD. The CD recorder allows digital aud

14、io signals to be recorded on music CD-R and CD-RW discs without compressing the digital signals, providing high quality equivalent to commercially-available CD (Compact Discs). CD-R (Compact Disc - Recordable) A CD-R allows digital signals to be recorded additionally after previous recordings until

15、the recordable time of the disc is fulfilled, but the signals once recorded cannot be erased. Also, once the disc is finalized, the disc can be played on other CD players* as well as on this system, but additional recording becomes no longer possible. CD-RW (Compact Disc - Rewritable) A CD-RW allows

16、 digital signals to be recorded additional after previous recordings until the recordable time of the disc is fulfilled, and the signals recorded can be erased and re-written, thereby making possible repeated recording on a disc. Additional recording on a CD-RW is also impossible once it has been fi

17、nalized, but a finalized disc can be returned to a non-finalized disc. This means that even a finalized CD-RW can accept additional recording when it is unfinalized. However, a finalized CD-RW cannot be played on ordinary CD players. It can be played back only on equipment which is compatible with C

18、D-RW. The difference between the CD-R and CD-RW discs are as follows. Recordable discs This system can record signals only on CD-R/RW discs designed for music. The music CD-R/RW discs carry the markings as shown below. Note that the system cannot record signals on CD-R/RW discs for use with personal

19、 computers. This system may not be able to record signals on certain music CD-R/RW discs depending on the disc characteristics. KENWOOD has confirmed the normal operation of the system with the CD-R/RW discs of the following manufacturers (as of October 2000). Non-recordable signals Other data than

20、audio signals, such as the CD-ROM signal, cannot be played and recorded with this system. When a disc containing variety of data formats, such as a CD Graphic or CD-TEXT is used, the system cannot record or play data other than audio data. The system can neither record or play compressed digital aud

21、io signals such as those recorded with Dolby Digital (AC-3) or MPEG. Recording and playback of discs recorded on other CD recorders Some of CD-R/RW discs recorded on other CD recorders than this system (including CD-R/RW drives of PC) may not be recorded or played by this system due to differences i

22、n the disc characteristics and recording characteristics (pickup, etc.). This system cannot record and play digital signals other than audio signals. * . Playback may be impossible with certain equipment. CD-RCD-RW TDK CORPORATION HITACHI MAXELL, LTD. MITSUBISHI CHEMICAL CORPORATION MITSUI CHEMICALS

23、, INC. SONY CORPORATION TAIYOYUDEN CO., LTD. Finalization (FINALIZE) Finalization is the final processing of a CD-R/RW to make it playable on the CD player*1 of this system and other CD-R/RW compatible players. CD-R.The finalized disc can be played on the CD player of this system as well as other CD

24、 players*2. As the disc becomes identical to ordinary CD, additional recording is not available any more. CD-RW.The finalized disc can be played on the CD player of this system as well as other CD-RW compatible players*3. Additional recording and erasure are basically impossible like the CD-R, but t

25、he disc can be returned to the status before finalization when it is unfinalized. Before Finalization CD-RCD-RW CD-R CD-RW Playback on CD player of this system *1 . The CD player of this system is compatible with playback of CD-R/RW discs. *2 . As the CD-R disc has lower reflectance than other music

26、 CDs, it may sometimes be unable to be played on certain ordinary CD players. Playback may also become impossible due to disc properties, dirt, scratch, stained pickup, condensation, etc. The CD-R disc may also be unable to be played on certain DVD players due to difference in the pickup wavelength.

27、 *3 . Playback may be impossible with certain equipment. *4 . This becomes possible once the disc is unfinalized. Status after finalization A CD-R/RW can accept recording of up to 99 tracks. More than 99 tracks cannot be recorded even when the disc still has a remaining capacity. The minimum recordi

28、ng time per track is 4 seconds.
