The company has been selling a rewritable 25GB Blu-ray disc since the beginning of the year and recently announced a 100GB prototype.
The 50GB disc with a double recording layer structure will be the centrepiece of TDK's presence at Internationale Funkausstelung, the world's largest consumer electronics trade show, in Berlin from 1-6 September.
"The introduction of Blu-ray disc is one of the most significant product launches in the company's history," said Jean-Paul Eekhout, TDK's European director of corporate strategy.
"Innovations such as hard coating and inorganic recording material have played an essential role in the development of the cartridge-free Blu-ray disc. "
TDK Blu-ray discs are manufactured at the company's Chikumagawa Techno Factory in Japan.
Recommended retail pricing is €35 for a 50GB BD-R (write once) disc and €45 for a 50GB BD-RE (write many) disc.
The initial Blu-ray disc standard allows for 25GB single-layer discs and 50GB dual-layer discs.
