Whats the difference between a Sparse disk image and a read write disk image?

I'm just using these to encrypt some documents.

a sparse disk image is one that grows as big as necessary (but doesnt shrink unfortunately).

I have created a sparse disk image of 40MB but it doesn't expand as I add more files, why is this?
