Appendix A: Working With CD-ReWritable (CD-RW) Discs
In addition to working with CD-Recordable (CD-R) discs, the DIRECTOR
EC can also rewrite CD-ReWritable (CD-RW) discs. CD-R discs are write-
once and can be read on any CD audio player, CD-ROM and MultiRead
DVD-ROM drive. CD-RW discs can be rewritten to as many as 1,000 times
and are read using MultiRead CD-ROM (usually 24x and faster) and DVD-
ROM drives.
CD-RW Supported Formats
The DIRECTOR EC can duplicate CD-RW discs written in most logical
formats (ISO 9660, audio, etc.) but not those created using the Universal
Disk Format (UDF). CD-RW discs using UDF are produced by packet
writing software (such as Roxio DirectCD, CeQuadrat PacketCD, Prassi
abCD etc.). Because UDF discs cannot be read by all CD-ROM drives they
are not a good choice for distributing data.
CD-RW Recording Speed
CD-RW copying speed is determined by two factors - the CD-RW writing
speed of the recorders installed in the DIRECTOR EC and the maximum
speed rating of the discs themselves. CD-RW discs are manufactured with
an internal speed code, which is checked before copying begins.
