They were the predecessor to CD's

Laserdisc technology, using a transparent disc, was invented by David Paul Gregg in 1958 (and patented in 1961 and 1969). By 1969 Philips had developed a videodisc in reflective mode, which has great advantages over the transparent mode. MCA and Philips decided to join their efforts. They first publicly demonstrated the videodisc in 1972. LD was first available on the market, in Atlanta, on December 15, 1978, two years after the VHS VCR and five years before the CD, which is based on laserdisc technology. Philips produced the players and MCA the discs. The Philips/MCA cooperation was not successful, and discontinued after a few years. Several of the scientists responsible for the early research (Richard Wilkinson, Ray Deakin, and John Winslow) founded Optical Disc Corporation (now ODC Nimbus), and that company is still the world leader in optical disc mastering technology.

Remember mini disc?
Hero999 said:I wonder how much information one of thos dics could hold since they can't have used compression as computers weren't powerful enough back then.
Hero999 said:I wonder what resolution they used. I can't have seen them using full PAL resolution since a 90 miniute film with CD quality sound will take 65.65GB of storage space!
