You do not want to use an SSD/NAND for carts/long term storage.

You want to use ROM.

They don't "burn" discs in a factory. They actually "stamp" discs instead, that allows for hundreds of thousands of disks to be created in quick succession at a low cost.
Where-as burning a disc requires discs with special chemicals/composition layers and takes "time" to add the data to the disc itself.
Plus those discs can and will degrade faster than a stamped disc.

They aren't records. How do you 'stamp' a disc?

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.
