zzB, this was a hot topic a while back. Generally, jewel cases are an excellent way to store disks. However, at least a few people have stored many DVDs (one would be Drpino–up to around 1500 DVDs for up to 15 years) in CD/DVD wallets with no trouble (no data corruption) provided that those wallets were stored in a cool, dark place (also not subject to huge variances in humidity), away from direct sunlight. One person who recommended those ‘toolbox’ looking storage cases (where the DVD/CD is stored vertically [also recommended]) would be chas----. He tested them extensively and found the dye on the back of the DVD was not scratched from repeated removals (around 500 repeated one-after-the-other put-in/take-outs), and he even checked with magnifying glass or something else to look for even hairline scratches–and there were none. So, you could buy those toolbox cases and provided you stored the case out of direct sunlight, in a cool place not subject to wide extremes of humidity, you should be in good shape, with no worries.
