Smartphones are creating a new culture of mobile connectivity. And they use lots of different components made by TDK!

TDK's multilayer chip components are significantly helping to reduce the size and weight of mobile devices.
Many types of noise suppression components made by TDK are also in widespread use, ensuring high-quality, high-reliability data transmission.

With the new LTE standard in mobile network technology, RF modules for multi-band mobile phones show great potential!


LTE (Long Term Evolution) is a next-generation standard in mobile network technology that will enable download speeds of up to 75 Mbit/sec. The problem is that many different standards currently exist for frequency bands from country to country and carrier to carrier.

standards vary widely from country to country

This situation requires manufacturers targeting the global mobile phone business to comply with a wide range of differing standards. Mounting components accordingly leads to many problems, such as higher costs, greater space requirements, and heavier phones.

more expensive, more crowded, heavier

To address this, the market needs high-frequency modules for multi-band mobile phones, where a single module can handle a range of different radio frequencies. TDK-EPCOS is strong in this area and is developing new products to meet these needs.

TDK leads the way in increasing the capacity of hard disk drives through the development of magnetic heads using advanced thin-film processing technologies.

Nanotechnology is employed to control manufacturing at the level of one-one millionth of a millimeter.
HDD heads are manufactured using advanced thin-film process technologies.
TDK's newly developed "thermal-assist" technology will usher in the age of one-terabyte hard drives for notebook computers.

A breakthrough in increasing hard disk capacity An entirely new way of recording. TDK's "thermal-assist" technology boosts the capabilities of a hard disk drive's magnetic head!


Advancements in computer hard disk drives are taking place at a remarkable speed, with capacities increasing at an accelerating pace. In the last 50 years, capacities have increased 100 million times!


How can the data recording capacity of the disc (platter) shoot up without a change in disc size? The answer lies in the miniaturization of the tracks (recording units) for writing data, which means greater recording density.

When the approaching limits of miniaturization started to become clear, TDK began working on a perpendicular recording method to replace the horizontal system that had always been used. In 2005, TDK succeeded in commercializing the world's first perpendicular recording method.


However, limits started to appear in the perpendicular recording method as demand for higher data recording capacity continued to grow. TDK then began working to develop magnetic heads for hard disk drives that use an entirely different approach: thermal-assist magnetic recording.

The day is not far off when surface recording density will exceed one terabit per square inch in a hard disk drive.
