Tape has it's problems too, but CD/DVD is not the answer in my opinion. I just recently converted nearly all of my CD's to FLAC and WAV files and it's really paid off. I can keep tons of tunes on flash and hard drives. It's truly amazing.
Just back up twice. I use a 8tB hardrive in raid 5, which gives some security, and backup to a portable 3 TB drive. That is above the internal PC storage. I have close to 1Tb in music files in flac,and the ripped cd's in a cool storage place, plus about 2k vinyl records. So there is some physical storage as well.
The demise of tape won’t be a big bang that results in a black hole through some instantaneous event. Instead, tape will die because it can’t follow or match current market conditions and requirements. Problems that limit tape’s popularity include mislabeling, labels that fall off, media failures, transport failures, library failures, media server failures, slow performance, risk of loss or theft, and the high cost of replacing, adding, or re-mastering tape for use by new generations. For all those reasons, users will simply stop writing data to tape; they’ll opt for disk instead. Every stronghold of value that tape once held has been supplanted by disk. Protection, performance, reliability, energy conservation, management, and cost all favor disk...Gartner estimates that 15 percent of all backups fail. Additionally, 10 to 50 percent of all subsequent restores from tape fail, depending on the elapsed time since the backup occurred. Restoring data from tape older than five years fails 40 to 50 percent of the time. Much of this goes unnoticed. Both Gartner and Storage Magazine report that some 34 percent of companies never test a restore from tape. Of those that do test, 77 percent experienced failures in their tape backups.

Since my raid 5 units in a 1ru rack casing sits securely in a rack, and consists of four drives where one is used for the raid backup, the chance of it crashing to the floor is likely to happen only in an earthquake of magnitude 9 and above. I welded the rack from 2 x 1" steel tube, and it weighs roughly 150lbs....
