TDK Corporation (TDK株式会社 TDK Kabushiki-gaisha), formerly TDK Electronics Co., Ltd (東京電気化学工業株式会社), is a Japanese multinational electronics company that manufactures electronic materials, electronic components, and recording and data-storage media. Its motto is "Contribute to culture and industry through creativity".
"TDK" is an initialism of the original Japanese name of the company: Tokyo Denki Kagaku Kōgyō K.K. (Tokyo Electric Chemical Industry Co., Ltd.). The company is listed on the Tokyo Stock Exchange and is a constituent of the Nikkei 225 and TOPIX indices.
TDK was founded in Tokyo, Japan, on 7 December 1935 to manufacture the iron-based magnetic material ferrite, which had been recently invented by Yogoro Kato and Takeshi Takei. In 1952 and 1957 they began production of magnetic tapes, with compact cassette tapes following in 1966; it is for these that the company is most widely noted. TDK used to manufacture an extensive portfolio of magnetic and optical media, including several formats of videotape and blank CD-R and recordable DVD discs until the recording business was sold to Imation in 2007.
In 1980, TDK developed a multilayering technology to create chip capacitors and inductors inside personal computers, laptops, smartphones, and other electronic devices.
In 1986, TDK acquired SAE Magnetics and introduced high-density recording heads to their product offerings.
Since 1997 TDK has gradually withdrawn from the production of compact cassettes. First with the MA-X and AR ("Acoustic Response"), then the AD ("Acoustic Dynamic") and SA-X line in 2001 and 2002 respectively, then the MA ("Metal Alloy") line in 2004. The SA ("Super Avilyn") and D ("Dynamic") lines were withdrawn in 2012 under Imation ownership. Industry trends see the company moving into new forms of media; in 2004 TDK was the first media manufacturer to join the companies developing BD post-DVD technology. TDK operated a semiconductor division in California for about a decade, but divested it in 2005.
In late 2007, Imation acquired TDK's recording business, including flash media, optical media, magnetic tape, and accessories, for $300 million. This also included a license to use the "TDK Life on Record" brand on data storage and audio products for 25 years. In September 2015, Imation announced that it had agreed to relinquish this license and would cease selling TDK-branded products by the end of the year.
Since the 2000s, TDK has turned its focus to the development, manufacture and sales of electronic components, HDD heads and suspension, and power supplies.
Beginning in 2005, TDK has acquired all manner of electronic device manufacturers including passive component developers, sensors manufacturers and power supply companies. These areas remain TDK’s focus today.
Since 2016, Shigenao Ishiguro has been President and CEO of TDK.
