Before the advent of Blu-ray Disk, hard drives and the recently added option for storage, Cloud, we had been using magnetic tape to record, store data and listen to quality songs. Do we still have them around in our homes? I guess not. That's because we think the cassette tape is dead. But Sony's new magnetic tape might make us rethink this impression. Or perhaps teach you how to build your own 185 Terabytes hard drive storage array for only $9,305. Its new magnetic tape could store 185TB of data in a single cassette tape.

This new tape storage capacity unseats the previous  record of 29.5GB of data per square inch a tape could hold. By comparison, the  maximum amounts of data a standard dual layer Blu-ray Disc can hold is 25GB per layer. This explains why video games nowadays come in at 50GB( an entire disc). But a magnetic tape stores half of the amounts of data a Blu-ray Disc can hold in a one little square inch.


Using a vacuum-forming technique known as sputter deposition to create layers of magnetic crystals, Sony created its new tape that expand the storage capacity of magnetic tape from 29.5GB to a whopping 148GB per square inch. That's eventually means that when you put the magnetic tape in a cartridge, a single cassette can store  185GB of data. Waoh! Again, that's 3,700 times more  storage than a Blue-ray Disc. Or for better understanding, 3,700 dual layer 50GB Blu-ray Disc. One of these Sony's new tape could store 5 more TB of data than a vast array of hard drives storage worth $9,305.

It's incredible. Now governments can spy and record everything we ever do on a single cassette tape(not my words).
