Mystery CD-RWs

I have two CD-RWs that I bought recently, one is a mini CompUSA 4x and the other is a no-name 74min 10x from

CDRID and EAC say that both are made by Plasmon, while the Lite-On Media Check prog says that the mini is Ritek/Philips and the 74min is Ritek.

Both have ATIP 97m 27s 10f and similar writing on the inner ring of the CD.

I emailed the shop4tech people and they said that their discs are made by Ritek.

Any thoughts?
