Any record will wear, maybe we should look to the laser turntables, they can play 33, 45 and 78's with a laser beam, and do not wear the records....wow.
Anyways, unless your record is very valuable, I would not worry about wearing out a record. If you properly store, clean and handle your records, change the steel needle, have your reproducer properly rebuilt, then you should have no problem wearing out your records. Get alot of them, maybe 100 average 78's from the acoustic era. You fiqure it you could play 10 records maybe in a hour (thats enough to play in a day), and you probably play the same record, 50 times a year, in 10 years you played it 500 times, I would say, you are doing good.
I go ahead and enjoy my talking machines, I play them records. If you are worried about losing a record, you should transfer it to CD.
