Digital Archiving - Preserving Tomorrow's Media for Today

AMC Technology Sub-committee Chair, Tim Halle, sent in this interesting article by Bob Lamm. .

Dave McCarn, WGBH's Chief Technologist, has a mission: He wants to come up with a permanent, universal digital file format for archived media. One that not only carries the original sound and image, but also transcriptions, production notes, authorship/copyright/royalty info, hypermedia links to other media files, etc. Once in this form, it would be free of the underlying tape technology it was originated on, permanently linked to the information that usually gets lost in paper files, and could be stored on the same general-purpose digital media we keep our e-mail and other computer-based files on.

Dave explained a little bit of this vision at our February 18 meeting at WGBH-TV. He pointed out that this was an issue of considerable importance to a station like WGBH: They have something like 150,000 reels/cassettes of one sort or another in their archives. Although WGBH takes great care to store these under optimal conditions, magnetic tape is inherently unstable, and the inevitable deterioration is starting to set in. In addition, WGBH also needs to keep a selection of old machines, also carefully preserved, in operational condition just to play back this media. These machines are starting to show their age and can't be expected to last indefinitely.
