Does anyone know what the numbers printed on the outside of a laser diode mean? ex...s1503c38c? Answered

I forgot which dvd drive I got it out of. I had two readers and one burner.  I do not remember which one it came out of but I can read numbers printed on the side of the case.

I googled "numbers printed on laser diode" and various permutations.  Nothing came up for me.

Thanks!

The numbers there are a manufactures code. What they mean if anything is only known by the manufacture. It may be nothing more then a date and batch number so they can track it if there is a problem with a batch.
