The concept is exactly the same as a record.
There are "pits" in the plastic layer just like a record.

The difference is how those "pits" are sent back to the hardware... A record uses a pin that is dragged over the pits... A CD/DVD/Blu-Ray uses a laser that bounces of a reflective metal layer.

And I quote: "In addition, CD burners write data sequentially, while a CD pressing plant forms the entire disk in one physical stamping operation, similar to record pressing."

Feel free to look at the manufacturing process on Youtube for a more visualized reference point.

Enh, mostly the same. Still 'burned' with a laser just done all at once unlike traditional burning at home. Whatever, it's all good.

The master disc is burned with a laser, the successive copies are "stamped" in a plastic mould.

This is different to consumer recordable compact disks which use a laser to alter a chemical layer.
