Could also use acetone but again these are dangerous and outside only things.
Pics and info if you do anything. Burning would be a bad idea since I live in town. Acids are a better idea, what about heat but not so much to melt the plastic? Like just enough heat to melt the glue or whatever keeps it together? I have a 15kw induction heater that could heat up the metal inside the disk too, maybe I can give it a try?

The street cred you'd get is worth way more than the puny amount of aluminum in them that'd be almost impossible to separate, like Zeta points out.

The total quantity of aluminum is likely only a few grams. It would be like trying to remove all the paint from your car in one piece. I was always told they had a very thin aluminum platter inside them, I could prove with is true sometime soon. I going to try the following to take apart the disks, hot air gun, air craft stripper, acetone/goof off and a 15kw induction heater.

jadefalcon wrote: I have a handful of rotted disks with no valve otherwise, If I recall right there is a aluminum platter encased inside the disk. Has anyone tried to remove the platter inside of a dead disk? I can't think of a way to do this without making a mess or using harsh chemicals extracting laserdiscs? I know your all thinking, why? Just something to mess around with and to pass the time. The micro-thin aluminium layer is exactly what deteriorated in the first place with a 'rotted' disc. Sure - pull the disc apart and learn something about their construction - but don't expect you're saving anything.......

signofzeta wrote: You were always told wrong then. There is no platter of metal so you will never prove that there is one. The plastic is the platter, the aluminum isn’t even .001”, I’m pretty sure, because it was spray formed and it’s reflectivity was it’s only needed feature. You can find videos of the entire Laserdisc manufacturing process on YouTube if you want to know anything or everything about it. CDs are nearly the same process. well now that kinda spoils the fun . I'll still give it a shot with some of the rotted disks I have.
