How do disks work in the context of video games?

Question

I understand how disks work with thing like movies, but how can a disk game memorize new information like a characters position in an rpg like zelda?

As far as I know, consoles do not burn information to the disks and memorising the information on a server is impossible for offline games so how do they do it?

Answer 1

Such video games would be restricted to keeping a save file locally on the console itself, perhaps on some kind of removable media such as a memory card. While much smaller in storage capacity than the game disks themselves the memory cards can be written to and erased on demand, allowing game states to be saved and transferred between consoles as needed.
