Tape in, bits out
I figure I've got about 500 cassette tapes, 100 open reel tapes and 75 microcassette tapes, some of which I would love to digitize. Among them are recordings of old radio (going back to the earliest 1960s), recordings of interviews or gab sessions, and other stuff I haven't bothered to label, much less catalog. For years I've avoided doing anything with most of them, because I don't want to subject the delicate media to any more loss or degradation than nature has already imposed. In the case of some cassettes, the mechanisms or containers are warped, missing pieces (the springy pads that press the tape against the playback head have fallen out of several cassettes) or otherwise in need of replacement or repair.
Anyway, I heard from a friend yesterday who wants to save her old recordings as well, and was wondering what approach I might recommend. Since I don't have an approach yet, I thought I'd pass the question along to the rest of ya'll.
I imagine there are services that do this; but I'm wanting to explore the DIY approach first. Any recommendations?
For what it's worth, I have a pretty-good Sony cassette deck, an Aiwa reel-to-reel deck (from the mid-'70s "Quad" era), but no surviving microcassette players.
