Loose Spring Found In Optical Drive Where Did It Come From Playstation 4

Chosen Solution

Ps4 wasn’t recognizing any discs so I opened it up. Heres what I found. A small black spring sticking to the magnet inside. I suspect it came from somewhere in the laser track or whatever but I’m not 100% sure. Any ideas? This is the cuh-1001a model.

There seems to be a spring to make sure the laser sled’s plastic tooth properly engage with the jackscrew that drives it.

you can see it between the jackscrew and the laser.
