One of the sellers of "JVC / Taiyo Yuden 16X" has a line stating "Manufactured by Victor Advanced Media Co., A subsidiary of Taiyo Yuden & JVC."
Inquiring minds want to know, so I dug up the following tidbits, showing what looks to me like a tangled web of corporate intrigue in the "strange" Oct 2008 JVC/TY joint venture (JV):
Interview with JVC President Masatoshi Inui, revealing many things including this: "Last fall , Taiyo Yuden significantly reduced its production and workforce...."
Another item of note is his answer to this question:
CDROM2GO: How did JVC Advanced Media USA become a leader in the disc industry?
Masatoshi Inui: JVC Advanced Media USA is a wholly-owned subsidiary of Victor Advanced Media Co., Ltd (Japan), which is a joint-venture between JVC and Taiyo Yuden. We have been globally engaged in the recording media business for a long time, including video tapes (VHS), magnetic tapes (for professional use), and recordable CD/DVD media.
Our parent company, Victor Advanced Media (Japan) has a strong technological capacity for the development of recording technology, and has manufactured high quality optical discs at several manufacturers worldwide including Taiyo Yuden. As one of our suppliers, Taiyo Yuden can confirm our highest quality requirements and continue to supply high quality discs for business use customers. JVC Advanced Media USA is exclusively selling Victor Advanced Media’s products from while controlling its design, specification, quality, and so on. Taiyo Yuden no longer sells optical discs in the U.S. I'm curious about his mention of "business use customers"?
Here's a strange JVC announcement in 2009 (after the JV in 2008), which includes this section:
Lots more online info on Victor, JVC and TY along these lines that just might make you say, "WTH!?"
