How well are the tapes holding up???
Well I started recording in 1981 and can say they are holding up well. I always stored them properly. I remember there was all this talk that tapes wouldn't last 10 years. Horse-hockey, well maybe if you stored them on the cars dashboard. . I payed $16 when tapes went on sale back then, that was a bargain.
I have 8 tracks from the early to middle 70's that even though I had to fix the foam that fell apart still play well. Same for cassettes I have from the late 70's and beyond. Tape was a good media for longevity. I have read lately that tapes can easily out live DVD or CD burns. I guess only time will tell.
I have to admit one thing 6 hour recordings I made from my dish and very good sources will blow away most of the digital over compressed garbage we get today in picture quality. One thing I do love about analog is the lack of digital artifacts, none what a concept .
