This second one is a good demonstration of our record-changing players from back in the good old days before we learned how to spell "CD" or "DVD". If you washed the records with mild soap and warm water, and rinsed them well and dried them off with a lint-free towel, and kept a good quality needle pickup on the tone arm, these things lasted quite a long time. I've got LPs here that are now 50 years old, and are still quite playable. Those old 78-RPM disks though were much more fragile because they were very brittle. The newer vinyl ones are much more durable. Experts even tell me that the music recorded on a good quality 12-inch LP often sounds richer and fuller than music recorded on DVDs.
That's because the 12-inch discs have bigger grooves and stronger sound.
And there's more....... check out this one....
