Gotta love the BBC’s tech coverage. The linked article talks about attempts at Imperial College to make an optical disk with a terabyte of storage capacity (equivalent to about 120 DVDs, or 240 DVD-Rs). The Beeb say you could fit 472 hours of video on this, equivalent to the whole of the Simpsons.
Now, there are currently 15 series of the Simpsons, each with around 24 episodes lasting for around 25 minutes each, making a total of 150 hours of telly. It’s possible the show will run for another 30 seasons (and presumably season 16 has already been made), but even so this seems a little presumptious.
More irritatingly, the article ignores the most important change in digital video since DVD launched – which is that compression technology has improved so much you can now squeeze 25 minutes of DVD quality video into less than 200MB, so you only need 72GB, nine DVDs, or 18 DVD-Rs, to store the whole of the Simpsons anyway. If you go for VHS quality instead of DVD quality, you can cut the file size down to 50MB, which gets the entire show onto 2.5 DVDs anyway. And by 2010, compression will have improved still further, by the power of Moore’s Law.
I guess the author’s suffering from DVD-price-based brainwashing (‘in the crazy future, you’ll be able to get £1000s worth of telly on a single disk… what do you mean you can do that already?’)
