They make a metal mould which is then stamped into melted plastic to make the pits and lands and then coated with a metal film to make the reflected backing, filling in the pits. This makes manufacturing of millions of disks extremely cheap since it takes seconds per disc. Burning commercial disks individually in thousands of burners would be way too slow/expensive. permalink fedilink source parent hideshow 2 child comments replies: [–] homesweethomeMrL@lemmy.world 6 points 2 years ago (1 child) Wow just like vinyl, sort of huh?

This is why when when CDs originally came out, the industry kept saying "soon CDs will be super cheap since they're so much cheaper than manufacturing tapes!"

This is also why they kept trying to make laserdisc (and RCA's CED) be a thing, since they were cheaper to mass manufacture by stamping than prerecorded video tape's slow dubbing process. It was thought that prerecorded video tapes were always going to be too expensive (originally they were like $100 a tape, hence the rise of video rental stores) permalink fedilink source parent hideshow 4 child comments replies: [–] homesweethomeMrL@lemmy.world 2 points 2 years ago before they realized people were still perfectly happy paying $15 for a disc.

The large format for art, all futuristic lookin’ - but all media degrades so maybe M-disc in laserdisc size? We’ll probably have crystal storage before then i guess. permalink fedilink source parent
