KES-400A
Description
KES-400A is the laser mounted in KEM-400AAA slide, in Blu-Ray Drive model BD-400 with daughterboards BMD-001, BMD-002, and BMD-003. Used in CECHAxx, CECHBxx, CECHCxx, CECHExx CECHGxx PS3 models (all retail Fat PS3's manufactured before october 2007)
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.
I'm not sure what the above paragraph refers to. The pickup in the photos has a single laser diode can with the CD, DVD, and blu-ray diodes inside, and a lens on a single micro-stepper linear stage.
