A good tape system is quite reliable; that's why tape backup is still the gold standard in enterprise class installations. The initial outlay for such a system can be higher than CD-RW, but the incremental cost of adding media is lower and the media itself has a more proven track record than CD-RW.
The biggest drawback of a tape system is time taken to restore a file. When disaster strikes, the last thing you have is leisure time to find your data. Having the most critical stuff backed up to (multiple copies of) CDRWs is a definite win.
I actually do a "best of both worlds" method: backups are dumped to HD every night, and once a week moved to tape. That way anything within the last week is still readily available on the HD dump, and anything older than that remains available on tape.
