Well fella I didn't mean to get you riled up. lol.
I always made cassette copies of LP's back in the day myself. I had a nice Technics deck and a Kenwood deck. Still have a cassette deck...Sony I think....whether it still works or not I have no clue. Sat so long now the pinch rollers are probably rock hard. I have a 10 pack of TDK tapes never opened.
When I went into the Army, my wife and I had somewhere in the neighborhood of 300 LP's, which were stored in a garage closet. By the time I got out of the service, the majority of discs had succumbed to some sort of mold/rot that discwasher would not remove. Evidently there was a lot of moisture in that closet!
Extreme circumstances, granted, but no physical media is immune from some sort of degradation.
