Blank CDRs -- What's long-term viable while cost effective?

[Muse]

The Verbatim 700 MB 52x 80 Minute Branded Recordable Disc CD-R - 100-Disc Spindle has fairly good reviews, but the "most helpful" are from ~10 years ago, and like some of them say, a lot can change, they are apt to not be now what they once were. You can pay $2/disk, some reviews say, for gold substrate material. A review said that's overkill since they've improved the plastic over the substrate. Reviews say the quality hasn't been consistent. As was said in the past (AFAIK, the same reviews I read years ago when trying to decide!), disks made in Japan or even Taiwan are apt to be more reliable than ones made elsewhere. Just perusing Amazon I can't tell where they are made. I have used disk ID programs to evaluate disks I have purchased, but of course I can't do that with disks I haven't bought yet.

Of course, there's a lot to choose from in blank CDRs beyond those Verbatims.

I bought a 100 disk canister of Sony CDRs at Costco a few years ago, I can't recall a problem, but I'm almost out of them. Just pick up another canister at Costco?

I use them mostly for music. I don't want to find them unreadable in time. What are your ideas on what 100 CD spindles you would purchase?

I have maxell cdr from early 90s that are still working. And they hage been sitting in the car for the last eight years all year round.

At $.17 a disk, who cares how long they last?

Homer, did you really just say that? Saving those pennys does no good if the disc fails 5 years out when you need it.

If you are looking for long term, there is no holy grail. Apparently BDR is pretty damn good though. You pretty much need to do multiple copies + yearly testing to make sure you detect and replace the bad copies before you run into a situation where you have no good copies left.

I recently went through and re archived dvd's to some portable hard drives for better accessing, found a number that the plastic top had been separating from the top foil layer. One of them completely. Thankfully the hub and outer ring were much secure and I was able to read it without the disc coming apart in the drive. These were generally taiyo's value line of disc.
