CMC Magnetics Corporation (Chinese: 中環股份有限公司) is a Taiwanese company that manufactures optical discs. Established in 1978, its factories are located in Taiwan, China (Memorex, HP, Philips, TDK, Maxell) and Hong Kong (Memorex, Philips). In December 2015, Taiyo Yuden, one of the inventors of the recordable CD and inventor of the original cyanine dye for CD-R, sold its optical disc brand and intellectual property to CMC Magnetics, ending its own production in Japan
CMC produces CD and DVD storage media products, including CD-R, CD-RW, DVD-R/RW, DVD+R/RW, DVD-RAM, and floppy diskettes. CMC produces the Mr. Data line of optical media, which is or was commonly rebranded and sold by HP, Maxprint, Imation, Memorex, Philips, TDK, BenQ, Verbatim Life Series, Staples, Office Depot, Datamax, Optimum, Auchan and other OEM brands.
After Taiyo Yuden sold its optical disc manufacturing business, CMC started the CMC Pro line of optical media, a new line of optical media based on the Taiyo Yuden technology that CMC acquired after Taiyo Yuden left the optical disc market
This past June, JVC/Taiyo Yuden made the announcement that they will be stopping production of all optical media products at the end of 2015 and making a complete withdrawal from the market. JVC/TY’s withdrawal left a huge void in the professional media market and CMC quickly seized the opportunity to purchase the technology and fill that void. CMC has committed to produce all current JVC skus and maintain the unmatched quality and consistency the professional market demands. With the help of Taiyo Yuden engineers, CMC has built specialized, dedicated production lines using the exact same processes, raw materials and strict quality control measures to ensure the TY quality is maintained. JVC/Taiyo Yuden blank media has been the exclusive choice of professionals since optical media first came to market. In today’s high volume CD Recordable environments, professional users need the assurance that their choice of media will provide high performance, compatibility, and long term data integrity. CMC’s committment to upholding TY’s unmatched quality allows professionals to once again have access to blank media with the lowest failure rate, highest playback compatibility and superior printable surfaces. CMC Pro offers a wide variety of printable surfaces and has an option for virtually every type of duplication and printing equipment on the market.
