if your only looking at making a simple laser pointer and not a very bright one. then go ahead and use the diode you have. A dvd rewriteable must be used for a high power red.

Follow the directions at this link to make your own laser.

Out of curiosity...DVD drives use red diodes. DVDRW drives use high powered red diodes.

What strength diode would be present in the reader drives? I see them, all the time, in the broken drive pile.

The "reader" diodes are about 3.5-15mw max....I posted earlier different numbers, but loooked and found these numbers to be accurate.

Any chance you can post a pic? (set your camera to macro mode)
Many DVD drives are different and its hard to try giving you a generic answer. Its possible you have one of those tricky setups where the diode is not in a can, and from what I hear those are pretty much hopeless.

I've updated the original instruction to complete the walkthrough of the diy red laser.

Twisted - have you read the various walkthroughs available on the site ? If you harvested diodes from a CD drive, it is virtually pointless, as there is very little power to be had from those diodes.

To answer your "Now What" question - now, you put it all back together, and go get a dvd writer !

You can get cheap DVD writters via the web - check www.pricewatch.com for the best deals !

get a 16x or higher - and hope you do not end up with an "open can" diode.....

Okay - now you need to get an appropriate housing to put all the parts in ! I suggest getting the empty chrome housings from Aixiz on Ebay - they are worth the price !

The rest of the "DIY" is outlined in many many many threads on here - take a read, and then ask specific questions about the parts you do not understand....that is if you want to build it yourself - if you want someone to build one for you, then there are folks on here that could use the extra bucks, I am sure !
