Suggestion for CD filesystem for Backups

[Judith und Mirko Kloppstech <jugal@gmx.net>]

You can use CDs or DVDs for Backup purposes. 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.
