continuously reading from a disk each time you need to load a different section of the map.
This is exactly what many games do that deal with large worlds. Large games often take gigabytes to install to the hard drive and you can't expect the computer to handle all of that at the same time, it's far more practical to design a system that'll partition the world and process a reasonable amount of data. This often means the player's current area and probably the immediate surrounding area.
