How are professional disks made? Silver vs green.

[dragos240]

I ordered a new jaunty cd and it's silver on the data side vs green like burnable disks..... how does this work? Why do burned disks look different than store bought disks?

[sim-value]

Cause they are getting pressed

Not burned

Store bought CD's and DVD's are not made the same way.

They master CD is the only one that is die pressed. The clones are mold injected replicas.

Wow! That was very interesting! All that for a cd? COOL!

Professionally manufactured disks last far far longer than what you can burn at home.

You would be surprised on how many things are manufactured. The Discovery Channel has a show, "How it's Made." They take you through the process of manufactureing regular every day items. For me though, the most disturbing show was on making coffins.

Yeah, I'm a huge fan of that show. It's pretty awesome. And the theme song really gets me.

I thought the silver part of the disk is to reflect the light back, where as green, purple, glod is dye used so the laser can burn pits in its crystaline structure giving 1s and 0s, scrotched bits and not scortched bits. and re writables are burnt at a higher temperature to reset the crystal back to its original state.

it was somthing like that, i researched it a few years a go for uni.

the color of the cd is also reflects what the cd is made out of (material wise).
