Think it's more correctly to say that almost all Sony branded MediaTek chipset drives are made by Lite-On/Samsung.
With the fiasco 401/411 burners not beeng able to burn dash media Lite-On gave up designing sircuit boards for burners. The crappy MediaTek chipset causing the -R issues was still used though. :doh:
Heck, even my old Lite-On 812 burner circuit board (nowdays in my sons setup) is labeled with "Sony".
Nope, Sony to say never touched that circuit board, except for designing maybe. Sorry. :flower:
