Name those DVD Burner parts :) Answered
Hi guys and gals, I just ripped apart a broken pioneer dvd burner of mine (digging for the laser diode inside) Apart from some nifty fans, motors, springs etc. I also came across these inside the reading/writing head of the burner. One definitely is a laser. But as often pointed dvd burners tend to have multiple (2) lasers. Now I wonder which of these items is the second one? All of the three upper items were pointing inside the head and (via some mirrors and lenses) towards the lens shown at the bottom of the photo. So they all seem to be involved in either creating or receiving (reading sensor?) of the laser beam. Hope some brave soul can give me some hints on these.
