2D square barcodes on LD cans

[andyadams]

OK, I've found a barcode reader that reads micro QR, and gives me a "successful read" beep from the PHR803T micro QR code (as above). Now I just have to hook up a serial cable to it to see what data it is reading.. Hopefully this will shed some light on the actual part number of these diodes.

More later.

I've noticed that on all the BR LD's I've worked with (20mW Nichia, 100mW Nichia, PHR-803T, BDR-205), that they all have a very small square 2D.
