RITEK is one of the world's largest CD and DVD media producers.
RITEK-manufactured media is sold by different companies under many brands, including Fujifilm, Maxell, Memorex, Philips and Verbatim. It was also sold under the TDK brand from 2001–03, 2009-. Ritek is currently manufacturing DVD+R and Double Layer DVD+R media for TDK (2008).
RITEK's own brands include RIDATA, Traxdata, and Arita.
Confusingly, Rimedia, Ridisc and Rivision are not Ritek brands, but instead come from E-net, a company also known for Datawrite, Datasafe and Tuffdisc brands. Note that the Rimedia, Ridisc and Rivision brands do nevertheless sometimes sell discs which use Ritek media. (Other of their products use CMC Magnetics media.)
RITEK produces many types, sub-types and flavors of flash memory cards, including CompactFlash, SD cards, unbalanced SD cards, MMC cards, and RS-MMC cards. USB flash dongles ("EZ Drive") are also made by RITEK.
The first Taiwanese OLED screen was made by Ritek. RiTdisplay Corporation is a spin-off and member of the Ritek Group dedicated to display research and manufacturing.
RITEK Foundation was established by RITEK Corporation Chairman Jintai Yeh in 1999.
