> In 2021, lawyer and FOIA expert Michael Ravnitzky filed a request for copies of video footage of a lecture by legendary computer scientist Admiral Grace Hopper that were present in the National Security Agency’s archives. The NSA denied the request in May of 2024, stating that the agency no longer owned a machine capable of playing back the AMPEX video tapes in their collection. This is no longer correct. Once the denial was issued in May it was shared widely via HN and other outlets. This attention resulted in the video being digitized and put online in August 2024 (https://news.ycombinator.com/item?id=41356528a https://news.ycombinator.com/item?id=41356528a). As I and many others observed in May, there are quite a few specialist video firms as well as archivists, technology museums and private collectors of vintage video gear who have working 1-inch Type-C video player/recorders. It was by far the most common broadcast video tape format for well over a decade. Almost every broadcast TV station and post production house had several decks, so it's not even considered a rare or challenging format by any serious video archivist. The NSA's pro forma rejection was due to bureaucratic silos, budget and lack of motivation - not any technical inability to play that video format today. The staff charged with issuing the legally required responses to FOIA requests don't care about archiving, preservation or history. They are measured by clearing the request backlog and the fastest (+ cheapest) way to do that is to find any legitimate grounds for denial and check that box on the form - which they obviously did. Of course, the NSA does have other staff who are measured on preserving and disseminating the organization's history. Once the opportunity to preserve this media was brought to their attention, the right thing happened - and in this happy case it did so with surprising speed. The article should be updated because there are much better examples of vintage media being lost forever, such as acetate film reels including masters and camera negatives from early cinema. Although in that case, as with many others, the loss is most often due to improper storage of the media accelerating chemical decomposition - not any technical inability to read the media. In fact, I suspect there aren't yet many examples of loss purely due to no longer being able to technically parse a digital storage format. All the losses I'm aware of are due to things like bit rot, fading magnetic pulses and chemical degradation preventing recovering the raw signal in the first place. As evidenced by the heroic recovery and reconstruction of some of the earliest ever experimental television recordings, if the bits, pulses or grains still exist and there's motivation to recover it, we can usually find a way to capture the raw bits, pulses or waveforms and decode them into a modern format.
