Sony has developed a new magnetic tape technology that is touted to feature the world’s highest areal recording density of 148 Gb/in square.
This is 74 times more data compared to the traditional magnetic tape media. The nano-sized tape optimises the way it sends argon ions on to film in order to create magnetic material, and the 185TB of storage per cartridge makes a 5TB hard drive look like old tech.
Sony said that it is developing a soft magnetic underlayer with a smooth interface using sputter deposition and has managed to create a nano-grained magnetic layer with fine magnetic particles and uniform crystalline orientation.
It will mean that it is possible to record more than 185 TB of data per data cartridge.
Sony will jointly announce these results with IBM Corporation, which assisted with measuring and assessing the recording density of this new technology, at the INTERMAG Europe 2014 international magnetics conference to be held in Dresden, Germany beginning on May 4.
In recent years, the rapid recovery of data systems such as databases and data servers following natural disasters, as well as secure management of information has become more important,.
Cloud services and the creation of new markets to utilize big data have led to a growing need for a data storage media which can store large amounts of information.
The company said it will work towards commercialising this next generation tape storage media, as well as the development of increasingly advanced thin layer deposition technologies based on the sputter method, with the aim of increasing recording densities even further.
