Well, I picked up the TDK 50 pack. Total garbage, stay away from them. They're made by CMC magnetics, widely known for being crappy. Here's the ATIP info:
ATIP: 97m 26s 66f
Disc Manufacturer: CMC Magnetics Corp.
Reflective layer: Dye (Short strategy; e.g. Phthalocyanine)
Media type: CD-Recordable
Recording Speeds: min. unknown - max. unknown
nominal Capacity: 702.82MB (79m 59s 71f / LBA: 359846)
These TDK disks had over 8000 C1 errors on a full CD I wrote at 48x on my Lite-on. That's really bad. In contrast, the Fuji TYs have about 450 C1 errors for a full disk written at 48x.
