               The “digitisation factory” solution
               Problems with the solution
                    Digitisation
                    Factory approach
                    Digital Preservation

                     Decaying Obsolete 
                     Fragile
        Obsolescence: at least 2/3 of the material
        Deterioration: approximately 1/3 of the 
            material 
        Fragile media: roughly 1/4 of the material
       Overall: 70% of
        holdings have
        problems
       The Solution:
        digitisation

                     Obsolescence
               Videotape
                    2”; 1”; U-Matic: no playback equipment
               Film
                    Disappearing in post production
               Audio formats
                    Grams : no playback equipment
                    ¼” no longer accepted in BBC radio 
                       production and playout systems

                     Deterioration
               Videotape – decay of adhesive
                    2”; 1”; U-Matic (30% read failures at BBC)
               Audio – decay of adhesive
                    ¼” tape (depends upon brand)
               Magnetic sound tracks
                    Vinegar syndrome
               Other Acetate – other sources of acetic acid
               Decay of film splices
               General decay of polymer materials
