Epilogue:

The CD-R actually burns the data into the "Recording layer" surface of the disk. This makes it permanent.

The CD-RW has an electrostatic charge placed on the disk between the "Dielectric layers." That's why it can be erased - by neutralizing or "erasing" the "charge."

It's just like static electricity. Over a period of time (maybe a long time), this static charge can "leak-off" and the "data" is lost.

That is why CD-R disks are more reliable than CD-RW disks.
