From WikiHow: 

Disney’s vault system means putting certain movies on a moratorium so that they are not available for purchase or digital viewing until they are released from the vault. Generally, Disney puts movies in a seven-year vault hold and then releases them. Disney’s reasoning behind the release is that every seven years a new generation of 2 – 7 year old children comes of age and is ready to enjoy the films. Generally, two movies are released a year.

Others believe that Disney’s vault system was created to create a scarcity. Because the scarcity encourages people to rush out and buy the DVDs and Blue-ray disks when they are released, since they’re not available all the time.
