An ISO file has been burned into a blank DVD (in a Linux OS). Is there any commands in Ubuntu to check when the DVD was burned?
I mean the date that the ISO file was burned, I do not mean the date ISO itself was created.

1I don't think a DVD contains that information. The structure of a DVD, outside the contents of the data track, is basically just the table of contents (which says where the data track starts and ends) and error-correction data. And the data track is just the contents of the ISO file.– WyzardCommented Aug 8, 2015 at 4:57

ISO 9660 ?
Try dd if=/dev/sr0 bs=1 skip=33581 count=17 | hexdump -C
Example output:
00000000 32 30 31 32 30 38 32 33 31 37 31 33 34 37 30 30 |2012082317134700|
00000010 00 |.|

Is that going to be the burn date? Or the date that the ISO filesystem was created?– larsksCommented Aug 8, 2015 at 16:01

It's defined as "The standard specifies the field Volume Creation Date and Time as a numerical representation of the moment of the volume's creation, written to the 814th through 830th byte of the Primary Volume Descriptor".– steveCommented Aug 8, 2015 at 16:23

It seems it just reveals the date the ISO was created. Commented Aug 8, 2015 at 18:47
