[edit] Recording media
Blank CD and DVD media is made by That's Fukushima for the distributor START Lab. Media Products manufactured by Taiyo Yuden are considered to be some of the best among enthusiasts, and are also used by drive manufacturers and Sony PlayStation developers.
Taiyo Yuden's cakeboxes usually have a special form and a printed shrinkwrap foil (unlike other manufacturers using transparent shrinkwrap and printed paper cylinder). The inner rings of the CD-R products are frosted.
Taiyo Yuden branded products are not common outside of Japan (where Taiyo Yuden media has a market share of about 60%) but unbranded silver top CDs and DVDs are available from some online retailers. Rebranded Taiyo Yuden media can be found under Fujifilm, Fusion, Maxell, Miflop, Panasonic, Plextor, Sony, TDK and Verbatim brands [1]. In Japan, Korea and Greece, Taiyo Yuden is distributing its own brand "That's".
Taiyo Yuden made DVD media has the following media codes:
TAIYOYUDEN: 2x DVD-R, hub stamper code: GBxxxxxx
TYG01: 4x DVD-R, hub stamper code: GDxxxxxx
TYG02: 8x DVD-R, hub stamper code: GGxxxxxx
TYG03: 16x DVD-R, hub stamper code: GHxxxxxx
TYG11: 8x DVD-R DL, hub stamper code: BGxxxxxx (incompatibilities with burners with outdated firmware)
YUDEN000 T00: 2.4x DVD+R, hub stamper code unknown
YUDEN000 T01: 4x DVD+R, hub stamper codes: TCxxxxxx or TSxxxxxx
YUDEN000 T02: 8x DVD+R, hub stamper code: TGxxxxxx
YUDEN000 T03: 16x DVD+R, hub stamper code: THxxxxxx
Infosmart of Hong Kong, Optodisc of Taiwan and other manufacturers from Hong Kong, Macau and Taiwan have been making discs which illegitimately use Taiyo Yuden's mediacodes and are prone to degradation and data loss. If those discs do not have one of these hub codes, they are most likely fakes and should not be used.
Taiyo Yuden has also developed the Autostrategy technology, a learning mode for DVD burners, for Plextor.
