Power requirements of computer CD-ROMplayers differ widely. The heaviest one I have in front of my says it requires 5V/1.5A and 12V/1.5A. Another one wants only 5V/1A en 12V/400mA. So you'd better find out first what you really need.
The most simple way to make 5V out of 12V is using an 7805. Of course you need a type that can provide the output current you need and you will have to provide some some thorough heatsinking. You may have to throw away over
