A mind recording device hooked up to the brain to record and store all your thoughts and mental images?

Do you think a device like this could ever be invented? I'm sure many people have had epic ideas flash through their mind but before they could scribble them down on paper it slipped away into the recesses of their mind. Does anyone think a device can (or even will) ever be invented that records everything that goes on in your brain and stores it all for you to literally see in picture form with crystal clear accuracy of how it was in your mind? I imagine if it ever is the inventor of it will become an immortal legend like Einstein. But is it possible for anything like this to ever be developed?
