It has 1 lens with 2 laser diodes, one for CD/DVD and one for BluRay. It was infamouslly known for being prone to failure, this failure was caused by a mobile "glass prisma" that "bounces" the two laser beams (it works as a mirror located in between the laser diode and the disc surface), after this model the mobile part was removed and the laser beams are separated by using 2 different lenses.
It has a single can with the CD, DVD, and blu-ray laser diodes inside. The outgoing and return beams are separated by a pair of polarizing beam-splitter cubes.  The only moving parts are a lens on a micro stepper motor controlled linear stage, and the objective lens.

  • Notes:
    • The motors (disc spin motor and tray in/out motor) are compatible with PS3 too
    • The rest of the drive (slide, daugther board and mechanicals parts) are not compatibles with PS3
