I've tried to explain inconvenience of using R2R - nothing else. I don't have anything against analog but limited amount of available recordings made me concentrate on CD/computer playback. As for storing tapes in the attic - it is possibly the worst place to keep magnetic tapes since tapes are affected by high temperatures the most followed by temperature changes.
Kijanki, I speak from experience and I mentioned attics for a reason- tapes don't mind being heated up. In fact its a common practice in the studio to bake an older tape (with a polyester backing) as this chases moisture out of the tape and reduces sticking and shedding dramatically.
Once baked properly, the tape will likely play without shedding for months or several years before needing it again. Of course this practice only works if the tape is not totally shot to begin with...
I run an LP mastering operation; last year we did a reissue project of a local blues/folk musician (Spider John Koerner, for those keeping track, http://www.neros-neptune.com/spider-john-koerner-some-american-folk-songs-like-they-used-to-lp-cd/). The recording was not spectacular, but it was on reel to reel, stored that way in the attic of the artist since 1972. The tapes were in immaculate condition (surprise! -no baking needed!) despite being an early 'high output' formula.
Tapes don't mind being heated up one bit as long as its not excessive. Its a lot better for them than storing them in the basement! I still have cassette tapes in my old Bronco that are 30 years old and still play fine. I store them in the truck and they get heated (baked) there quite a lot. I have no doubt that is why they don't shed after all these years.
