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!

100million times in 50years!

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.

We

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.

One for multiple!
