TDK told the press it has developed a hard drive head which can write between 150 and 200 gigabits data per inch. To achieve this the company developed a tunnelling magneto resistance device using perpendicular recording.
With this new technology a 3.5-inch HDD platter will be able to hold as much as 250GB. Mass production of TDK's new heads is planned for early next year.
