Can I use a CD drive optical pickup as a robot's line tracking sensor ? . I don't know the anatomy of the optical pickup, such as : the laser diode pinouts and the photo diode pinouts...
 

I would recommend you to use a standard infra red reflection sensor instead such as the one on the attached image.

An interesting alternative would be a linear ccd-sensor + a miniature ccd-tv-lens. I have tried this and it works very well.
