Scientists Create DVD-Sized Disk Storing 1 Petabit (125,000 Gigabytes) of Data
Popular Science points out that for encoding data, "optical disks almost always offer just a single, 2D layer — that reflective, silver underside." "If you could boost a disk's number of available, encodable layers, however, you could hypothetically gain a massive amount of extra space..." R...
Popular Science points out that for encoding data, "optical disks almost always offer just a single, 2D layer — that reflective, silver underside. ""If you could boost a disk's number of available, encodable layers, however, you could hypothetically gain a massive amount of extra space..." Researchers at the University of Shanghai for Science and Technology recently set out to do just that, and published the results earlier this week in the journal, Nature. As Gizmodo offers for reference, that same petabit of information would require roughly a six-and-a-half foot tall stack of HHD drives — if you tried to encode the same amount of data onto Blu-rays, you'd need around 10,000 blank ones to complete your (extremely inefficient) challenge.
