I think Amedee has already clarified most of this, there's just one bit
I want to be more specific with:

Let's say you have a directory /media/music. In this directory are two
files: file1 file2

And you have a removable hard drive, with music on it. In this
directory are four files: song1 song2 song3 song4.

If you look in the directory /media/music/, you will see

/media/music/file1
/media/music/file2

If you mount that removable hard drive at /media/music, then when you
look in /media/music you will see:

/media/music/song1
/media/music/song2
/media/music/song3
/media/music/song4

file1 and file2 haven't been deleted, they're just inaccessible while
something else is mounted in their parent directory (/media/music). If
you unmount the removable drive and look in /media/music you'll see 

/media/music/file1
/media/music/file2

Again, song1, song2, song3 and song4 haven't been deleted, they're just
rendered inaccesible because they're not mounted anywhere.
