Recording on CD-RWs
A CD-R can have additional tracks added after recording has finished, but before finalisation. It is not possible to delete tracks from a CD-R, once recorded; neither is it possible to add any further tracks to a CD-R after finalisation.
On a CD-RW, tracks may be overwritten. The CDR-882 provides the means to delete certain tracks from a CD-RW (there are restrictions – see page 47). Like a CD-R, further tracks can be added to a CD-RW before finalisation, but unlike a CD-R, a CD- RW may also be “unfinalised” after finalisation has taken place, and tracks deleted and/or added.
The basic process of recording a single CD-RW is essentially no different from recording a CD-R. The display will confirm that the disc is a CD-RW once a disc is inserted. If there is already programme material on the disc, the number of tracks will
be displayed; once RECORD is pressed and the drive enters RECORD PAUSE mode, the track counter will increment by one, ready for the addition of the new track(s).
Disc types
CDs are recorded to CD-DA Red Book standard in the CDR-882 DualBurn Recorder using either CD-R (write once) or CD-RW (rewriteable) blank discs. Blank discs optimised for audio use are recommended for professional use, though the CDR-882 will accept standard “data” CD-Rs and CD-RWs as well.
HHB blank recordable media is recommended for high quality audio, as it is manufactured specifically for professional audio applications. The CDR80HS 52x disc is particularly suited to the high-speed drives in the CDR-882.
The CDR-882 is also able to play and record audio CDs with “encoded” formats such as Dolby Digital or DTS. No audio decoding for these formats is provided on replay, however the Dolby Digital or DTS bitstream is available in full at the digital outputs. Recording of such formats is possible either by using DISC COPY mode, or by connecting a Dolby Digital, DTS, etc., digital input signal externally. (Sample rate must be 44.1kHz and Input Dither should be disabled with such signals; see page 30 for more information about setting Input Dither.)
It may be possible to play discs which include non-audio content as well as audio; an example is CD+graphics. However, if the CDR-882 is used in DISC COPY mode with such discs, only the audio content of the source disc will be copied. Discs with CD Text content are fully supported by the CDR-882, however.
The CDR-882 only plays and records audio discs; other CD formats, for example computer CD-ROMs, cannot be played or recorded. No support is provided on playback or record for MP3, WMA, AAC, etc. files
Digital Recording restrictions
Almost all commercial digital source material is protected by copyright laws, and many CDs use copy control flags to limit digital recording of a source to one generation only. However, as the CDR-882 is a professional recorder the status of the copy control flag is ignored, and the status of the flag written to disc is adjustable.
This facility is only for professional use and must never be used to enable infringement of copyright.
The maximum number of tracks which can be recorded to a CD is 99.
The minimum allowable length of a individual track is 4 seconds.
Track numbers are automatically recorded to a CD along with the audio data, and incremented at the start of each track. The CDR-882 is able to create new tracks in several ways, based on IDs in the incoming digital audio (S/PDIF only), audio threshold, fixed time increments (useful when recording a long single programme), or manually. See page 33 for more details on how selection of the various options is made.
If recording digitally from a DAT machine some problems may be encountered as to the location of track numbers relative to the start of a track. In some cases, the start of a track may not be recorded, or the beginning of the subsequent track may be recorded on the end of a track. These anomalies are inherent in the DAT system and are a consequence of the accuracy achievable for inserting IDs into the DAT format using a DAT recorder’s Auto ID function. To avoid these problems, we recommend that Start IDs are inserted manually on the DAT tape whenever possible.
