I had a laser disc player. Actually two. One you had to load with the disc cover on,and the other you just loaded the disc which was the size of a 33 record.
We always rented the Cartridge kind, I can still remember when my uncle pried one open and we all saw the laser disk for the first time, (the hologram was still a few months away, remember the eagle sticker on the cover of national geographic?) My aunt let out this horrible shriek and told my uncle to "put it back! it will cause cancer!" those were the days.
