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 acronym of the original Japanese name of the company: Tokyo Denkikagaku Kogyo, (Tokyo Electronics and Chemicals).
TDK was founded in Japan on 7 December 1935 to manufacture iron-based magnetic material ferrite, which had been recently invented by Yogoro Kato and Takeshi Takei. In 1952 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 it licensed the rights to do so to Imation. Imation also now manufactures USB flash drives under this license.
Since 1997 TDK has gradually withdrawn from the production of compact cassettes. First with the MA-X and AR, then the AD and SA-X line in 2001 and 2002 respectively, then the MA line in 2004. The SA and D lines were withdrawn in 2012 under Imation ownership.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.
Sponsorship and advertising 
From 1993 to 1998, TDK were the sponsors of the English football club Crystal Palace, who were promoted to the Premier League twice during this era, though lasting for just one season before being relegated on both occasions. TDK also sponsored Dutch giant Ajax for several years in 1980s. It is a current sponsor of the IAAF World Championships in Athletics. It also sponsors activities and events such as those at The Cross nightclub in Central London, and since 1990 has had a prominent sign at Piccadilly Circus. TDK also owned a sign on One Times Square since 2000. The screen is placed under that of Toshiba and can be seen during the annual Times Square New Year's Ball Drop.
In 2002, the company's consumer electronics division was the presenting sponsor of the Third Annual Jammy Awards, with the TDK Live Performance of the Year award honoring the best live performance that was legally available on the Web as a free download. The award was given to the band moe. for their performance at the Bonnaroo Music Festival.
TDK operates a company museum at its Hirasawa plant in Japan.
