What is a digipak?

As well as making the music video, another part of our coursework is to make our own digipak to go with our chosen song. A digipak usually contains 6 panels and usually has the best design on the spine of the panel. On the 6 panels, there should be a front, a back, a spine, possibly a membership postcard or spine, a lyric section and a disk impression. Although, not consciously realising it you have already seen several digipak's in your life as they are included in the majority of all CD's.
