The phrase you are looking for is optical drive, disk drives are anything with a disk which would include a HDD.
You need to understand that these days most people use their PC as an internet surfing device and nothing more, and in that case buying something with the added $200+ optical drive tax is just plain insane which the salesmen have picked up on.
Obviously you still need at least one optical drive in your household because a good deal of media relies on them, but beyond that they are heinously unreliable, slow and loud, I always transfer anything I need from them to an external drive which works beautifully every time.
