How can it be recognised? i do have old (pre 2024) and new ones of these. I will open up a new 10pcs pack and provide a scan in a day (and save the old ones)

interesting

Please look at the alphanumeric code of these enterprise disks - on the inner ring of the disk on top (it's something like a Lot#).
If indeed non-Sony disks have already gone, I assume that the code will apparently be either a different format or with noticeable differences.

for example here are my retail disks SONY 128GB, bought from Amazon Japan had such codes:
in February 2024 slim 5 pcs- 16DJ132SA
in November 2024 cake 25 pcs -16DJ1608B
in January 2025 cake 25 pcs- 16DJ1608B

Similar codes are on many disks for example BDR-DL Verbat-Imf-000
Mitsubishi Verbatim -> CMC Verbatim:
Mitsubishi Kagaku Media: DBRF 606V...
Mitsubishi Chemical Media: DBRF 606W...
fresh CMC Verbatim: DBRF 0618..., DBRF 0619...

I have looked many scans of SONY NQ1-001 on this forum and on the internet in general.
the best scans were at 2x write speed, 4x worse, 6x usually even worse.
The scans at 2x are so good, I haven't seen 3 layer 100 gb disks with better results than these 4 layer Sony disks

Ritek discs no longer have the Sony information printed on them. Ritek/RiData discs have the same information.

I don't know if the packaging differs between these releases.

Thank you.
Very stable quality.
Have you checked the degradation of 2017, 2018->2025? Is there a noticeable difference by scans?

My first SONY 128 Gb is only 1.5 years old
