QR part numbers
 

Sony RW DVD optical deck , the only part ident seems to be a paper QR label
marked on the optics carrier.
5K08
0062
2630
QR graphic
and under the graphic
5K0800062 2630
Googling any of those numbers with or without the extra 0 produces nothing.
No other part mumbers seen . Is the QR world totally separate from the www
world? or just no info out there , full stop.
Is that extra 0 like lopping off the (UK anyway) supermarket shelf label bar
code number to match the actual printed on the product bar code label number
