  • $\begingroup$ Interesting. It never occured to me it would grab the disc from the edge. I always figured it was roller wheels on the top and bottom. $\endgroup$

These drives are called slot loading optical drives. The mechanical arm grabs the disc and draws into the drive. Below is an image that shows the mechanical grab arm.

    $\begingroup$ You might want to mention it's the little wheel on the bottom right, and it only grabs the disc by moving sideways which means it only grabs the disc after it has been pushed in past the halfway point where the diameter starts decreasing so a sideways push brings the disc inward instead of outward. or make a GIF! $\endgroup$
