DID vs. MID

[dbminter]

What exactly is the Disc ID?  The Manufacturer ID, of course, lists who made the disc, but the Disc ID has me confused.  The Disc ID seems to be the same for all the discs in the cake stack.

 

Thanks!

They're the same thing (in my eyes).

One disc format may favour naming the fields in the descriptor for that format as disc id and another may prefer manufacturer id.

I get 2 different values for MID and DID, though.  For instance, my Taiyo Yuden DVD-R have an MID of TYG03, but the Disc ID is 0@P-!-00, some apparently random text.

Different disc formats use different descriptors for the info.
