Sony has come up with a new material for the magnetic tapes, which will enable magnetic tapes to store data worth 185 terabytes. That is 74 times more than what a standard cassette tape can hold and if that is not enough for comparison sake; 185 terabytes of data implies that you will be able to store 3,700 Blu-rays on this tape. Sounds great, doesn’t it?
According to IT World; ‘To make the new recording material, Sony used a kind of vacuum thin film-forming technology called sputter deposition. The process involves shooting argon ions at a polymer film substrate, which produces layers of magnetic crystal particles. By tweaking the sputter conditions and developing a soft magnetic under-layer on the film, the manufacturer was able to create a layer of fine magnetic particles with an average size of 7.7 nanometers.’
