All Optical media (CD, DVD, Blu-Ray etc.) have pits and lands. These are microscopic and represent the binary information of the data stored on the disc. A land is reflective and reflects the laser into a sensor to register it as a I, but when the light hits a pit, it shatters and no reflection is received, thus a O is registered. There is much confusion as to which is a pit and which is a land, even some professional texts get it wrong, but this is the way I was educated.
The recessed area on a CD or DVD where data is stored. CDs and DVDs store data in lands and pits. The lands represent 1 and the pits represent 0 in binary computing. The bits are read by the disc drive that uses a laser beam to distinguish between the lands and pits based on the amount of scattering or deflection that occurs when the beam of light hits the surface of the disc

Flip the laptop over so that the rubber feet are facing up. Remove the screw in the center of the laptop with the picture of a lock near it. This is the only thing keeping the cdrom drive from sliding out of the laptop. If it doesn't come out easily, you may need to power up the laptop, open up the cdrom tray, power off the laptop (while the cdrom tray is still open) then repeat procedure above - however, you'll now have the cdrom tray to use as a handle to pull out the entire cdrom drive.
Each IDE connector on the board supports two channels per. (Two drives) The combination of drives can vary. For instance, hard drive-cdrom, hard drive-hard drive, cdrom-cdrom, ect....ect.
