It should come as no surprise that recent advances in big-data analytics
and artificial intelligence have created strong incentives for
enterprises to amass information about every measurable aspect of their
businesses. And financial regulations now require organizations to keep
records for much longer periods than they had to in the past. So
companies and institutions of all stripes are holding onto more and
more.
Studies show that the amount of data being recorded is increasing at 30
to 40 percent per year. At the same time, the capacity of modern hard
drives, which are used to store most of this, is increasing at less than
half that rate. Fortunately, much of this information doesn't need to be
accessed instantly. And for such things, magnetic tape is the perfect
solution.
Seriously? Tape? The very idea may evoke images of reels rotating
fitfully next to a bulky mainframe in an old movie like Desk Set or Dr.
Strangelove. So, a quick reality check: Tape has never gone away!
Indeed, much of the world's data is still kept on tape, including data
for basic science, such as particle physics and radio astronomy, human
heritage and national archives, major motion pictures, banking,
insurance, oil exploration, and more. There is even a cadre of people
(including me, trained in materials science, engineering, or physics)
whose job it is to keep improving tape storage.
Tape has been around for a long while, yes, but the technology hasn't
been frozen in time. Quite the contrary. Like the hard disk and the
transistor, magnetic tape has advanced enormously over the decades.
