I'm getting various conflicting information on RE and just plain R discs.
BD-RE's use the same phase change principle as CD and DVD-RWs, right? I
think somebody on here said that the phase change would be better for
long term storage than the dye used in standard R's.

Can somebody set me straight?

Phase-change is better, but a consumer-grade (read: trash)
media like BD is not suitable for any form of archiving.

Is there such a thing as archival quality BD? What about supposedly
high quality Japanese BD media?

Archiving is difficult.

Yes, it is. The only long-term archival media are professional,
archival-grade tape. Alternatively, you can use spinning disks
with distribution, replication and regular data checks. I do the
second.

There used to be MOD, but nobody cared anout their data enough
and it is basically dead today, except for a niche for digital
medical images, which have to be archived for 10 years.

And no, BD is unsuitable for archiving by design. The supposedly
"high quality" media are still consumer grade.
