How to Burn tapes with a Green laser pointer

Step 4 Burn the tape with a green laser

Get a green laser pointer, and any one over 150mw or 200mw is okay while certainly the more powerful the laser is, the easier for it to do the job.
I used the 200mw Gehenna seriese green laser from http://www.laserto.com/green-laser-pointer.html.

certainly, the laser that used in the video (not mine) may be over 200mw green lasers from Highlasers.comHighlasers.com
