a laser reads the microscopic bumps on the disc... in interperats a bump as a 0 and a the non-bumps as a 1... that makes a string of 1s and 0s... witch is then caltulated by the cpu and so on and so forth...

that question is so vague and confusing. a cdrom is not the thing doing the work. The CD-rom DRIVE is the piece of equiment that's doing the work. First of all, the cdrom is the round piece of plastic we all know that u buy at a music store or whatever. It has data written on the reflective side. You can't see it, it's just there. The drive is the hardware that reads the data written on the disc, and watever the "system" ur talkin about plays the data for you. The drive is a little box with a laser on the inside that slides back and forth on the diameter of the disk to access different parts of the data written on the disc surface. In the drive, there is also a motor that spins the disc very fast. It's similar to a record and a turntable.

There is one data cable connected and one power cable, data cable to read data and power cable for power. The rest works exactly as a hard disk only that you may not be able to write on the cd rom, if it is a ROM.

It shines a laser through the disk as it spins and reads the holes that were burned into the disk.
