They did that in the late 70s. They were called LaserDiscs and held about 60 minutes of video per side in the most common encoding format.

- happycube 7y agoSome LD trivia: - It was the only consumer format that provided standard NTSC/PAL SD video without reformatting. Macrovision didn't work on them either so there's no copy protection. - Most LD's have digital sound, which literally is CD audio - not just the bitrate but the analog encoding and digital metadata as well. - The disks were expensive to produce (a dual-sided disk in low/moderate quantity was about $20) and if the glue wasn't done Just Right, the disk would degrade/rot over time. (The majority of surviving disks are just fine today... but some of particular interest to people, like the Domesday disks, aren't!)
- Animats 7y agoYes, I know. That's why I wrote that. It would be perfectly feasible to record analog audio on a LaserDisk. You could even record it as FM, since you have lots of extra bandwidth, to get more dynamic range and less noise.
