I don't see any trace of this file online. Normally, if it's a relatively well-known file, if you search for it in google, you'll get something like this. With comolc.dll I'm not getting anything. At the worst, you could delete it and then if a program needed it, you can reinstall that program. But let's see if anyone else has any suggestions.
Just had a thought: Maybe you could do a search for it in regedit. I think a lot of programs list make mention of dlls they use somewhere in the registry.

Go to a notebook service centre/Pc store and get a new laptop DVD drive. That'll be the most cost/time effective way to go. It's usually pretty simple to swap out drives on a laptop, undo a screw, possibly unlock a catch.
