Ritek but RICOH MID and design if it's currently sold retail. (Still a made by Prodisc small first batch exist. But it's unlikely that these are from that small batch.)
If you have a picture of the package I could confirm 100% if it are the ones with RICOH MID or PRODISC MID.
Bestbuy -> RICOH
there less reliable as MKM/MCC/VERBATIM media. But still okay if your drive supports them right.
Still I personally would recommend the verbatims over them. If they don't work then the drive just sucks as a dual layer writer.
I've only burned a couple RICOHJPN D00 discs... (Fujifilm brand)
1st disc in Toshiba SD-R5372: Burn process completed. Produced result: Unreadable disc (Fails transfer rate test in various drives).
2nd disc in NEC ND-3500A: Burn process completed.
Produced result: PI/PIF levels look decent. Transfer rate test has some slowdowns near the layer break. DVD Video on the disc plays fine in my Philips DVP-642.
