Hello.
I have an old Sony crx230ee CD burner(that writes 32x on CD-RW and 52x on CD-R) and I took the diode out, do you know by any chance what is the wavelength and the mw for this?
Type the model information into google and you should be able to find a spec sheet for the burner and that should give you some information.....but in the end it will be IR and dangerous. If you decide to use it be cautious.
