IBM recently demonstrated a new record in magnetic tape storage capabilities. With this new milestone, scientists “discovered that a single tape cartridge has the potential to store about 580 terabytes (TB) of data.” To help put that into perspective, IBM says, “580 TB is equivalent to 786,977 CDs stacked 944 meters high, which is taller than Burj Kalifa, the world’s tallest building.”
Pushing the limits of tape technology through the invention of new products and materials, “IBM achieved 317 GB/in2 (gigabits per square inch) in areal density on a prototype strontium ferrite (SrFe) particulate magnetic tape developed by FUJIFILM. This is approximately 27 times more than the areal density used in current state-of-the-art commercial tape drives,” the announcement states.
The work is the result of a 15-year collaboration between IBM researchers and FUJIFILM and, according to IBM, reaffirms the role tape will play in a hybrid cloud future and in meeting emerging demands.
