From the article: It also questioned why Radio-Canada was preserving its master recordings after making digital copies but CBC had opted to rely only on digital copies
This statement shows a lack of understanding of the problem. Old audio recordings can still be played. Old video recordings from the early VTRs[1] are going to be unplayable soon: the people who have the skill to refurbish an old VTR are well into retirement age now. There are only a handful of the original VTRs still operating.

- KC8ZKF 9y agoRadio-Canada is the french language arm of the CBC. It is television and radio, not just audio.
- ixf 9y agoVery old audio equipment is in a similar boat - I know archivists who are prioritizing stuff for digitization based on the number of tape head hours they think they've got left in older machines.
- pbhjpbhj 9y agoIs contact absolutely required in such old machines - I wonder if you could float the tape using, say, air [1], ultrasound, or silicon spray, or even just carefully fitted wheels in order to maximize life of the head itself. I'm surprised generic non-contact magnetic readers haven't been developed for retro tech given the prevalence of magnetic storage tech for HDDs.

- fencepost 9y agoI'd wonder more if a newer more modern head could also be used on the same tape at the same time (a few inches over on a slightly extended tape path), with the output of the "original" used to train software to interpret the higher resolution data coming from the new head. Seems to me that might in some ways be similar to some things required for software defined radio signal processing.
