They do error correction, everything is fine, until the errors get too much, than everything is lost. This is a nuisance for a backup, especially because normal people don't have the hardware to measure errors, jitter and the like. Suggestion: Why not write a file system on top of ISO9660 which uses the rest of the CD to write error correction. If a sector becomes unreadable, the error correction saves the data. Besides, a tool for testing the error rate and the safety of the data can be easily written for a normal CD-ROM drive. The data for error correction might be written into a file so that the CD can be read using any System, but Linux provides error correction.
