Great post!You're right about the problems with vinyl and tape. Of course they're vulnerable. Of course vinyl wears and can skip pop and crack. Tape is sensitive to demagnetization, drop-outs, bleed-through and wear. But then again, the "sampling rate" of vinyl and tape is much higher than that of CD's, or even of SACD's or DVD's.
And, yes, I still have some old 5" diskettes. Even have some 8" diskettes. Better still, I have the drives to run 'em on. Also have 9-track NRZI tapes and some 10Mb and 277Mb removable disk packs. One has 2 platters and the other has ten, both are a nice portable size of 15" and as thick and heavy as a bowling ball.
Gotta love nostalgia, yeah!
