Whats the best CDR Media?

Most media is good.

Just store it properly, let no water get near those disks!

Seal em tight or something.

I haven't heard bad stuff about archiving them as much as water/(ech) Mold damage.

Sony

I've been buying Sony CD-R's and CD-RW's for years and never had a problem with them.

The best media by far is from a company called tayo yuden. they actually manufacture i believe 80% or so of all cdr stock in the world. There is a grading scale for CDR's that dictates their bulk sales prices, so "A grade" CD's are kept by them to sell at a premium mostly to album mastering houses and recording studios. B-D Grade CDR's are usually sold to other compaines such as TDK, Sony, etc. the complication to this is that CD quality control can change from batch to batch, based on the success of the dye process and so forth. For burning personal CD's Tayo Yuden is a bit of overkill IMO, and can be difficult to consistently obtain. I find myself constantly changing CD brands based on sales personally, unless I am burning CD's to go to mastering, in which case I always have a pack of TY's on hand to get the best quality burn. If you're ever unsure of the quality of CD's that you're using, CD Analyzers are a wonderful thing.

I've had mixed things with Sony media not being read in many CD players so I tend to stay away from them. Memorex is always really good for me, though. TDK is pretty top notch, too. Just stay away from those stupid stacks, though, since half of them get all scratched up since there is no protection to keep them from damaging each other and you will end up with 100s of random discs without enough cases to go around to protect the ones that do survive.

The TY's can be ordered through specialty shops such as Sam Ash or Guitar Center; essentially anywhere that has a pro audio department.

i've been using cheap spindles of 100 CD-Rs for a couple of years... no problems. i usually get the cheapest i can find, around AUD $40 for a 100 spindle.
