Why is a DVD a good medium for preserving images?
As the name indicates, it is “Digital” technology, which is the technology that is quickly replacing the analog technology utilized by older videotapes and home movie film. It is less susceptible to environmental impacts and does not degrade with every playing. It plays as clear on the 100th time as it does the 1st time. Unlike analog playback devices, digital playback devices do not touch the surface of the medium. Copies made from digital technology do not lose clarity when they are copied. It is easier to move through (clicking on chapter marks rather than fast forwarding and reversing) and easier to store, For a more detailed discussion of why preserving to DVD is a good idea, see WHY TRANSFER?
