what software did you use to check your CD-R?
The hint is in the paste from the program.
You can see a test here:

Here's how MInfo sees them:
Drive Type = CD-RW
Disc Type = CDR (B-)
Lead In = 97:22:67
Lead Out = 79:59:74
Nominal = 702.83MB (79m 59s 74f/LBA:359849)
Manufacturer = Daxon Inc.
Cur. Speed = Wrt(52X),Rd(52X)
MInfo is a work in progress. Sony buys media from different sources, so don't depend on each spindle being the same.
