I scavenged the laser unit from an old DVD RW (benq 22x max). I read in internet that CD burner laser would be infrared hence invisible and DVD burner laser would be red. I soldered wires with both lasers (not removed from the unit) and powered (li-ion cell, 22 ohm R in series) to find the powerful DVD burning laser. But I found both lasers emitting red drawing similar current ( 70 to 80ma with different brightness).

I'm confused why both are red & which one is the DVD burning laser that I'm looking for!
What is the power rating of that Laser diode?
Can anyone pls advise me?
