Toshiba announced this week that the company has developed and produced media for hard drives with a storage density of 2.5 terabit per square inch. This is almost five times the storage density in the latest hard drives offered by the company today.
Toshiba will present the technology under the Magnetic Recording Conference 2010 today.
The company has adopted a solution which is called bit Patterned Media (BPM), which is a magnetic storage medium that consists of parent cells that each store one bit. In traditional hard drive technology stored each piece across a few hundred magnetic grains. With the storage density that is now been reflected, each magnetic point or cell will be less than 10 nanometers, which is not easy to achieve with current process technologies.
Toshiba has developed a manufacturing method that uses a type of patterns that control an array of self-fit end points, and produced a BPM with a servo pattern that consists of punktmatriser and data track with overall points. Toshiba will further develop the technology to achieve storage densities of 5 terabit per square inch.
According to Computerworld.com Toshiba expects that the first hard drives based on the BPM will come on the market in 2013.
