Again - Poles always require a pair. I think you guys may be confusion slots, poles, and pole pairs.
Pole is the indentification of either the north or south end of a magnet. A pole pair consists of 1 North and 1 South magnet pair. Slots are the empty spaces between the teeth (what the coils are wound around). So if you characterize a motor you typically mention how many slots, how many phases, how many poles (SPP). There are a lot of other things to look at as well, but those are basic and necessary for determining whether it has a good winding factor or not.
A CD ROM motor is not a great example to use when looking at motor designs because they are typically 2 phase motors rather than the far more standard 3 phase motor. From your post it is a 12 Pole 9 Slot brushless permanent magnet machine. A 2 phase motor will have higher winding factors with different slot per phase per pole configurations than a 3 phase motor.
