There are two types of taiwan made TDK for 8X DVD+R, one is CMC-MAG-E01 or CMC-MAG-F01and the other is RICOHJPN-R02-03. Many people think the RICOH stuff is superior to the CMC stuff. Not sure about DVD-R though.
Telling between the two has become something of a black art . Have a look at the beginning of this post on another forum page which has some pics and info on telling the two apart.
Attached below is a picture of what the ricohjpn 25 piece spindle looks like. Notice that there is no spacer sponge piece. The stuff you can get might look a bit different as TDK seems to use slightly different packaging in different parts of the world.
