Return of 'cassette tapes'!

Are cassette tapes dead? Wait...before reaching any conclusions you should know the importance of this object (generally used in 80s and 90s to play music) in the 21st century.

Researchers at Fuji Film and IBM have created a prototype cassette that works as a storage device, storing up to 35 terabytes of data or about 350 lakh books' worth of information—on a cartridge that measures 10x10x2cm.

The data is stored on a strip of magnetic tape that has been coated in particles of barium ferrite.

However, it looks like end-consumers are not going to get access to these cassettes; as these tapes are currently developed for big data storage use. According to New Scientist, these cassettes would be available to companies with huge server farms.

The cassettes are actually the opening act for the new IBM computer called the Square Kilometer Array (SKA), the world's largest radio telescope, whose thousands of antennas will be strewn across the southern hemisphere. Once it's up and running in 2024, the SKA is expected to pump out 1 petabyte (1 million gigabytes) of compressed data per day.
