Ferrite was originally invented and developed in Japan!
Ferrite is a magnetic material invented in 1930 by researchers at the Tokyo Institute of Technology. TDK was founded in 1935 with the aim of commercializing this innovative locally developed electronics material.
The Institute of Electrical and Electronics Engineers (IEEE), an international academic society related to electricity and electronics, recognizes technological achievements that have contributed to society and industry as IEEE Milestones. In 2009, the Development of Ferrite Materials and Their Applications by TDK and the Tokyo Institute of Technology received the award, becoming the 89th IEEE Milestone worldwide and 10th in Japan.
IEEE Milestone plague
The SD cassette tape was used on the Apollo 11 mission in 1969,
when humankind first set foot on the moon!
TDK developed the first Japanese-made cassette tape, revolutionizing music life. The tapes were a massive hit in the global market, and the TDK brand became a household name around the world.
The multilayer chip inductor is an essential component for making
mobile phones and smartphones smaller and thinner.
TDK developed the world's first multilayer chip inductor from the original idea of not winding but rather building up layers of wires. Even today, this invention is still contributing to the creation of smaller, lighter electronic equipment.
TDK has developed technology able
to control minute sizes of one-millionth of a millimeter!
Hard disk drives (HDDs) are used as large-capacity recording media in devices such as personal computers. In the field of magnetic heads for HDDs, requiring nanoscale thin-film technology, TDK possesses the world's highest level of technological prowess.
When it was originally founded, TDK was called Tokyo Denki Kagaku Kogyo. This name was rather long, however,so in 1983 it was changed to the simpler and more familiar TDK, taken from the first letters of the first three words (Tokyo, Denki, Kagaku).
The TDK logo uses triangles and squares to represent electronic computers and magnetic materials (substances with the property of adhering to magnets) and expresses the meaning that TDK "connects important parts of the electronics industry." Combined with the company name, it is the symbol guaranteeing the quality of TDK products and services.
