Sony develops tech for 185 TB magnetic storage cartridge

The magnetic tape recording still keeps up the value by innovative research by Sony. Sony has developed a soft magnetic underlayer with a smooth interface using sputter deposition and could succeed in creating a nano-grained magnetic layer with fine magnetic particles and uniform crystalline orientation.

This achievement helps for magnetic tape storage media supporting storage density of 148 Gb/in2 (gigabits per square inch). This areal recording density is equivalent to approximately 74 times the capacity of current mainstream coated magnetic tape storage media, and makes it possible to record more than 185 TB (terabytes) of data per data cartridge, as per Sony.
