Why can a hologram reproduce all the scenery even if there is only a small part left?

You can easily understand that holographic pictures are recorded in layers;

So even if most of it is damaged, we can still see the whole picture of the original object in this hologram from the remaining half. Because each film records different information, it can be said that each part can see all the information;

For a simpler example, a holographic negative is like a window, and the scenery is the scenery outside the window. If the negative film is damaged, others block most of the windows, but you can still get closer and see the scenery outside from the remaining unobstructed places, because this part of the negative film records the whole landscape information!
