CD are made of two parts plastic and polycarbonate (the shiny part) the bottom side is just plastic and the top side is where all the data it. The CD drive uses a laser that reads the polycarbonate through the plastic. So you look at the top part of the CD and its missing some of the polycarbonate your definitely going to get skips.
Clockwise (right), when observing from the back side (the side not being read)of the CD.
the CD drive has lasers which read the CD, so the CD has pieces that can be read.

I would say that a CD-ROM is a form of input, as it is "read only memory" and the data on it can only be read, but not written to. If you're talking about CD-R/CD+R drives, then those would be considered both input and output, as it can read from a CD, and writes to CD.
