What is a Digipak?

This is the Wikipedia definition of a digipak;
"Digipaks typically consist of a gatefold (book-style) paperboard or card stock outer binding, with one or more plastic trays capable of holding a CD or DVD attached to the inside. Since Digipaks were among the first alternatives to jewel cases to be used by major record companies, and because there is no other common name for Digipak-style packaging made by other companies, the term digipak or Digi-Pak^[2] is often used generically, even when the media holder is a hub or "Soft Spot"^[3] rather than a full plastic tray."

CD Insert

What I consider a digipak to be is a limited edition CD that has fold out flaps and extra album art, posters, lyrics, etc. for example the "Death Magnetica" by Metallica. this is part of there limited edition album for the latest album "Death Magnetica". You can see the insert booklet for the CD case, it has an interesting pattern going all the way through making it more of an experience that a piece of reading material.

Some digipaks might also include special download able content such as limited edition songs, images, games or even videos.
