The layers got separated so the cd is no longer reading.

The rainbow-like colors on the undersides of CDs are caused by the interference of light waves as they pass through the thin layers of the CD's surface. The patterns are formed due to the way the layers are structured and reflect light. It's a result of the physics of light interacting with the surface of the CD.
dual layer means there are layers of pits and lands on the dvd
now it includes higher density discs and multiple data layers.
CDs crack in a microwave oven due to the presence of metal layers within their structure. When microwaved, these metal layers can produce sparks and generate heat, causing the plastic material of the CD to warp and crack. The uneven heating and rapid expansion can lead to structural failure, resulting in visible damage to the disc. Additionally, the microwave's electromagnetic waves can disrupt the integrity of the CD's data layers.
This is not practical, it is sandwiched between two layers of plastic and is so thin any attempt to remove the plastic will rip it in small pieces still sandwiched between the plastic layers.
A CD (or compact disk) is made up from several layers of plastic, each doing its own function. If you take a microscope and take a look at a CD, you will notice this is true. Somewhere in the middle of all of these layers you will find the data layer (which is where the music is kept), and it is where the music is stored as digital information (data). Secondly there are the tracks of the disc, which is what the disc reader sees when it is reading it, and it does so through its optical eye, by using lasers to detect the data layer on the CD.
No, CD Drives and CD Burners are two different types of optical drives on personal computers that perform different functions regarding compact disk media. CD Burners are optical drives can write data on a burnable disk. CDs are comprised of thin layers of dots computers use to burn information on. CD Burners are equipped with a special laser that burns binary code onto the CD's surface. CD Burners can both read and write CD disks. CD Drives are not equipped with that special burning device, and have only a laser that can read the information stored on a disk. They can only read CD disks.
Absolutely ! The playing surface of the CD is the silver layer - which is sandwiched between two layers of clear plastic. You could wipe it with a damp cloth - even scrub it with a nail brush - and it'll still play properly !
Answer: How dual layer CD drives workCheck out this website: http://computer.howstuffworks.com/cd-burner.htm The main difference between a single layer and dual layer CD is that a dual layer CD or DVD has two layers of film on which data can be written to. One layer (the bottom one) is semi-silvered so that depending on the intensity of the laser, data can be read on each surface. The laser adjusts its intensity accordingly to which layer it want to read/write from.
