2 CDs, difference of 32 sectors in the last track - different media?

I have a case when 2 CDs contains the same recordings (the same Accoust IDs), but disk IDs are different because the last track length has a difference of 32 sectors (less than 0.5 seconds, so even not visible when comparing track lengths by recording time).

One of this CDs already exist in MusicBrainz: https://musicbrainz.org/cdtoc/G1C.YAx5kh8rDjL_2_oRvczkWws-

Full TOC for the CD referenced above:

1 24 350063 182 21030 36710 41832 53795 67832 81682 108900 121080 137110 157620 181547 193752 203047 213422 232347 257607 273580 276295 286225 300345 301617 315930 326625

The second CD I own, Picard calculated the following full TOC:

1 24 350095 182 21030 36710 41832 53795 67832 81682 108900 121080 137110 157620 181547 193752 203047 213422 232347 257607 273580 276295 286225 300345 301617 315930 326625

The only difference is in the last track (3rd number in the lists above): 350063 vs. 350095, that is a difference of 32 sectors.

So the CDs are very similar, but there is a slight printing difference in the last track. Is the difference small enough to consider both CDs to be essentially the same media with a slight printing variation? That is, should I create a completely new media for the second CD, or re-use existing media and add the second disk ID to it?

If it matters, the second CD is from a different release, so minor printing differences are possible.

The discIDs are not copied if you reuse the existing medium, anyway (that still creates a new medium for the new release, only that it takes all the existing medium data as a starting point). So just reuse the media, then add your discID to the medium on your CD :slight_smile:

There is most certainly a different CD matrix as well so you should indicate your matrix info in your new release annotation, to help distinguish.
