My DVD is separated into layers! Please help!

Today I was doing cleaning, and the clumsy me brought down the cabinet = =|||The DVDs were thrown onto the floor and I found out that one particular DVD separated into halves. T.T

The bottom layer has separated 1/3 from the upper layer and I can’t seem to play it in my computer.

This DVD has a lot of photos of my family during vacations and family functions. Unfortunately I did not do a backup copy… Please help!
