By far, the most critical aspect of burning CDRs for CD players is burn all tracks
in one session and
to use 74 minute CDRs (older CD players cannot read the narrower 80 minute tracks
reliably).
I am not going post the 74 minute thing again (third time).
I don't think laser wavelength plays a role between CDR and CD but I could be wrong.
