First off, I would suggest taking a look at x-cd-roast 
(http://www.xcdroast.org/).  It makes burning much easier.

You are burning the cd's correctly.  Not all cd drives can read CD-RW 
disks.  Some very old cd-rom drives even have trouble with CD-R's.

They can all read the pressed discs that come from a manufacturer.  CD-R 
and CD-RW use different methods to record data and different laser 
frequencies.  

If you need the disc to be readable on as many systems as possible, burn a 
CD-R (not RW).  This still won't help you with pure DVD drives or very old 
cd-rom units, but should work everywhere else.
