TDK was founded in Japan during the 1930s, but became really famous during the audio cassette era. They've moved successfully into the digital age, and one of their most notable recent achievements is the ultra-hard surface coating that makes Blu-Ray technology usable. (The tracks are so fine that even minor scratches would soon make discs unreadable without the coating).

Even when it comes to more everyday technology, you know that you can rely on TDK!
