Just uploaded recently. It shows an interesting example of NBTV compressed to work within the bandwidth of a normal 45 RPM record. He also touches on early recordings by Baird and mechanical TV

One records plays for 10 minutes. The disc spins with 1,500 RPM, for the picture it uses a special extra fine diamond, which will be polished before every use. The grooves are 40 times smaller than on a normal record. If you would combine that old technology with VinylVideo, full HD 90 minutes recordings on a 30 cm disc should be possible. But it wouldn't be cheap...
