Although I can't completely understand your question, I will try my best...
Since Apple introduced the PowerBook G4s, Apple has used the following optical drives:
DVD-ROM drive (I don't know which one that is)
Combo drive (CD-RW/DVD-ROM), manufactured by Matsushita (Parent company of Panasonic), model number CW-8121
SuperDrive (CD-RW/DVD-R), manufactured by Matsushita, model number UJ-815/816
So your drive is probably a CW-8121.
