Something like that, you mean?  ;-)

If it were mine, I'd discard the drive.  I'd recable it first, make it
cd[01].  If that doesn't work, and you still can't mount a manufactured CD
with it, get a new writer.  

I don't think your media are stale.  CD players fail remarkably quickly
(to this old fart, at any rate).  I don't know about dirt; I figure the
laser gives out.
