No drive region locked status

[iron2000]

Used the CDVDinfo tool to check the region status but the program shows nothing beside the "Drive region locked:".

Used the save info function and got this:

DRIVE VENDOR : SAMSUNG
DRIVE PROID : DVD-ROM SD-616F
DRIVE REVISION : E100
VENDOR SPECIFIC : HPD

RPC2 SCHEME : NO

CDRW WRITE SUPPORT : NO
DVD-ROM READ SUPPORT : YES
DVD-R READ SUPPORT : NO
DVD-RAM READ SUPPORT : NO
DVD-R WRITE SUPPORT : NO

How do I intepret these data?
