Overview
Ritek Corporation is a Taiwan-based technology manufacturing company whose best-known business has historically been the production of optical storage media. Its product scope has included compact discs, recordable and rewritable CDs, DVDs, Blu-ray discs, archival media, flash drives, and removable memory cards such as CompactFlash, SD, and MultiMediaCards. The company has also developed or manufactured passive-matrix OLED displays, ITO glass, touch-panel components, solar modules, high-precision plastic products, and selected nanotechnology and biotechnology-related products. The company grew out of the plastics and recording businesses established by Yeh Ching-Tai. In the 1950s, Yeh operated Min Li Plastics, producing items including plastic cigarette cases and polyethylene milk bottles. An unsuccessful attempt to use electroplating to improve plastic products led him toward copper and nickel plating for vinyl-record stampers. This experience supported expansion into record manufacturing and studio operations during the 1960s and 1970s. By the mid-1980s, Yeh anticipated that digital formats would transform recorded music and recruited engineers associated with Taiwan's Industrial Technology Research Institute to develop compact-disc manufacturing capabilities. Ritek was established in 1988. In May 1990 it manufactured Taiwan's first compact disc, with technical support from the Mechanical and Systems Research Laboratories of the Industrial Technology Research Institute. The achievement positioned Ritek at the center of Taiwan's emerging optical-disc industry. During the 1990s the company expanded its production footprint and product range, making Taiwan's first CD-RW and DVD, followed by the first DVD-R in 1997 and DVD-RAM in 1998. It also established international production, sales, packaging, and subsidiary operations in markets including Australia, the United States, the United Kingdom, Germany, Japan, and North Africa. Ritek became a public company in Taiwan in 1996. At its peak in the optical-media era, it operated at substantial international scale; in November 2005 it was reported to hold approximately 20 percent of the rewritable-DVD and CD-RW market and to be the world's largest disc manufacturer. The company supported industry and copyright initiatives, including the Compact Disc Manufacturers Association, and obtained early ISO quality and environmental certifications within Taiwan's CD-manufacturing sector. The business later diversified beyond optical discs. Ritek entered OLED production in the late 1990s, manufactured Taiwan's first OLED in 1999, and established RiTdisplay as a dedicated passive-matrix OLED business. It subsequently supplied OLED products for applications including wearable devices. The company also entered solar technology through alliances and affiliated businesses focused on thin-film and other photovoltaic modules. Additional activities have included touch panels, ITO glass, logistics, packaging, diamond-like carbon coatings, precision plastic injection, and nanotechnology. Ritek's brands and associated product names have included RiTEK, RiDATA, Traxdata, Smartbuy, RiBEST, ARITA, imation, and Plextor. The company has also maintained licensing, manufacturing, and strategic relationships with international technology and media companies. In 2018 it became Panasonic's only overseas production partner for Archival Disc, and in 2019 it entered a licensing agreement with Imation. By 2020, the company was reported to have approximately 5,900 employees. Ritek's present identity therefore combines a legacy optical-media manufacturer with a broader group of electronics, display, storage, and energy-related manufacturing businesses.
History
Ritek's origins trace to Yeh Ching-Tai's plastics and recording activities. Yeh established Min Li Plastics in 1952, initially making plastic consumer and packaging goods. After an unsuccessful attempt to electroplate plastic with chromium, he applied copper and nickel plating to vinyl-record stampers. This led to record manufacturing, studio operations, and the development of technical expertise in recorded media. During the 1980s, Yeh recognized that digital formats were likely to replace analog recording technologies. He imported advanced recording equipment, consulted Japanese technical specialists, and recruited engineers from Taiwan's Industrial Technology Research Institute. The group initially worked with basic plastic pressing before moving toward compact-disc manufacturing. RITEK Corporation was founded in 1988; its English name combines the ideas of “right” and “technology.” In May 1990, Ritek produced Taiwan's first compact disc with assistance from the Industrial Technology Research Institute. It joined the IFPI Members Foundation in Taiwan in 1991 and expanded internationally during the following decade. Production facilities or related operations were established in Australia, the United States, the United Kingdom, Germany, Japan, North Africa, and other locations. The company went public in Taiwan in 1996 and broadened its product portfolio from replicated CDs to recordable and rewritable formats. Ritek manufactured Taiwan's first CD-RW and DVD, followed by the first DVD-R in 1997 and the first DVD-RAM in 1998. In 1997 it signed a copyright-verification agreement with Taiwan offices of the Music Publishers Association and became the first Taiwanese CD manufacturer to obtain ISO 9001 certification. It later obtained ISO 14001 environmental certification and QS9000 certification. The company also supported the formation of the Compact Disc Manufacturers Association, which sought to strengthen copyright protection in CD replication. The optical-media business reached significant international scale during the early 2000s. In 1999, Ritek participated in a German CD-R joint venture with Philips and established U-TECH Media as a major Taiwanese prerecorded-media manufacturer. In 2005, the company was reported to be the world's largest disc manufacturer, with roughly one-fifth of the rewritable-DVD and CD-RW market. It subsequently added Blu-ray and other higher-capacity formats, while continuing to sell products under brands such as RiTEK, RiDATA, Traxdata, Smartbuy, RiBEST, and ARITA. Diversification became an important part of Ritek's development. The company produced Taiwan's first OLED in 1999 and created automated OLED production lines in 2001. RiTdisplay was established as a dedicated OLED manufacturer, later supplying passive-matrix OLED products for applications including wearables. Ritek also invested in ITO glass and touch-panel businesses, including AimCore Technology and RitFast. Ritek entered solar energy in 2008 through a strategic alliance with Scheuten. PV Next was established in 2009 for thin-film copper-indium-gallium-selenide photovoltaic manufacturing, and Ritek Solar later worked with SolarEdge and presented IM-series modules at Intersolar Europe. A Ritek solar module received a Taiwan Excellent PV Award in 2016. The company continued to develop specialty storage and electronics products. Its USB flash drive received an iF design award in 2008, M-DISC DVD and Blu-ray products were launched in 2013, and a RiDATA OTG flash drive received a technology-trends gold award in 2017. In 2018, Ritek became Panasonic's only overseas Archival Disc production partner. In 2019 it entered a licensing agreement with Imation. Ritek was reported to have approximately 5,900 employees in 2020. Its wider group and investment portfolio has included storage, displays, logistics, coatings, precision plastics, solar modules, and nanotechnology-related entities.
