What is a safedisc, or securerom?

i have been hearing people talk about this, but i dont know what the safediscs are. also I have battlefield 1942 secret weapons of world war 2, and everytime i try to play it with the no cd patch it says put in a cd. Do I need to burn it with alcohol to make it work, thanks
