Ritek started to get attention among the DVD+R and DVD+RW media users by selling Ricoh-code Ritek-media media. HP and many others also started using the same Ritek media to sell under their names.
It was only later that Ritek caused confusion for everyone including the resellers by mixing them with “Ritek R01” and “Ritek R02” media.
All Ritek media I get via Lite-On IT are ricohjpnr01 or ricohjpnr02 because Lite-On is one of Ritek’s important customers. It changed like this:

Though DVD Identifier says 1x and 2.4x for all three, they support 8x, 8x, 12x, 4x, and 12x writing with TS-H552B TS00 respectively. The “Top” means the label side of each disc. The five types mentioned above are all what I got to be bundled with Lite-On DVD writers.
Just for comparison, here is still another T02 under Fusion 4x DVD+R brand name and the next is for TYG01 under Fusion 4x DVD-R brand name.
