New super writable DVD(ish) disk stores 128,000 GIG of data!
The article describes the disc as 1 Petabit in storage, but you need to divide that by 8 to get it in bytes, so 128,000 gig of storage. Which is pretty good.
They're using a 3D effect to pack in 100 layers of data to achieve this density. The problem is, this is 'researchers from...' In other words, 'We've done this in a lab! Er... lab model.' We don't have a working prototype shown, we don't know what kind of read/write speeds, we don't know longevity or durability.
In other words, it's sort of vaporware. Could be really nice if it happens, if they ever start showing off production samples, when we can believe a little more of it. Show me an entire season of General Hospital on a single disc, I'll be impressed.
Of course that would require a new series of DVD/BR players, but for something like that, could be worth it. Could even return disc burners to desktop PCs. Or not.
I am reminded of a similar piece of vaporware from the late '80s/early '90s, someone claimed to have created a laser-written crystal lattice storage form, think something along the lines of the little data cartridges they carried around in Star Trek TOS. I think they were claiming something sized along the lines of 35mm slides. Promised amazing storage density at the time, which by now might be laughable. But never saw the light of day.

Wikipedia indicates a 36 mm × 24 mm frame of ISO 100-speed film contains the equivalent of 20 million pixels. If we use black-and-white film for longevity (silver halide on polyester is used in archives with a 1k year life expectancy), that's 20 megabits, or ... only 2.5 MB.
Better than my old floppies, but not as good as I had hoped.

Sadly, a lot of Ifs stand between the announcement and reality. We shall see what becomes of it.
