•Variable and fixed packet recording; typically used by back-up software and Drive Letter Access software to add files and folders at a time, instead of tracks/sessions at a time.
Applications
CD-R and CD-RW discs are each ideal for slightly different applications. Both can be recorded with the Spressa CD-ReWritable recorder. CD-R discs can’t be erased, but are compatible with standard CD-ROM drives and CD players. CD-RW discs can be erased and re-written, but have some inter-change limitations. Here are some typical applications for both discs:
| Data | | | CD | Personal |
| Distribution | Back-up | Archiving | Prototyping | File Storage |
| | | | | |
CD-R | • | | • | • | |
CD-RW | | • | | • | • |
Media Compatibility
Due to the different makeup of CD-R and CD-RW discs, these discs have different reflective qualities, and can be used with the following units.
CD-R | All CD-ROM drives and CD players |
CD-RW | Multi-Read and CD-RW compatible |
| CD-ROM drives and DVD-ROM drives |
Most newer drives are Multi-Read drives which have the capability to read stamped CD, CD-R and CD-RW discs.
Recommended Media | |
CD-R: | Sony 74/80 min. CD-Recordable disc. |
CD-RW: | Sony 74/80 min. CD-ReWritable disc. |
To achieve trouble free 8X recording speeds, be sure the CD-R media is certified for 8X recording.
To achieve trouble free 4X CD-RW recordings, be sure the CD-RW media is certified for 4X recording.
Reliability
The CD-RW Recorder has a mean time between the following (MTBF) rating of as high as 100,000 power on hours (POH) at 25% duty. 25% duty means the CD-RW Recorder is in actual use a quarter of the time the unit is turned on. MTBF is an average failure rate based on the total power on hours divided by the drive Annual Failure Rate. A failure is any malfunction of the drive that prevents you from using it. This includes failure to power up, load or unload a CD, and read or write data. Faults are not considered failures when they relate to incompatible software or discs, or from mishandling and/or abuse.
Reliability ratings are derived from a large statistical sample, and are not indicative of the performance of a single unit.
