Re: [ARSCLIST] Storing Mini-Discs
Back eons ago when I first started using digital hardware/software to
edit motion pictures, the MO was considered to be a less expensive
storage option (with its drive) than hard drives. It's hard to believe
that a 450 MB hard drive would have about cost $1000 then. But, the
technology for MOs wasn't perfected then (they became corrupted) as I
lost some audio/video files in trusting them. I would guess that has

You raise good points about the M-O structure of MDs. I hope I was
careful to address the player issue in my original post. Your friend
may be correct, but I believe most life-time analysis has been done on
industrial M-Os not MDs. I'm sure not trusting my stuff to MD. I
consider it a capture medium, not an archival medium.
There have been both manufacturer and independent testing about the
longevity of the Phthalocyanine dye used in the MAM-A discs. It is
claimed that this is a Mitsui patent.
I suspect that the writing drive is an issue for both MDs and CDs.
Jerry can chime in with more details here.
I'm using managed disc drives for much of my current storage and I am
a fan of managed storage in the data domain. I am not a fan of
dedicated formats in general for archiving. I make an exception for
gold audio CD-Rs as they are readable in computers as well as audio

Richard, I can't speak to the future players, but a radio friend of
mine thinks that MDs are MORE archival as they have magneto-optical
recording and may last longer than the only-chemical CDs. He took the
time and trouble to transfer 20 years of weekly programs to MD for
the permanent archive on this theory.
Do you think he might be wrong? Discounting the availability of
players, for the sake of discussion. You are probably right about
that the way things are going with the players though nothing is
gospel any more.
Thanks for your opinion!

Digitally transfer them to two CD-Rs and store the CD-Rs. Or better
yet, if you have a managed digital archive that can accept them,
store them in that.
I don't think many of us think that MDs are archival. I wouldn't
worry about an archival box for a medium that probably isn't
archival. I don't think we can expect the long-term availability of
MD players as compared to CD players.
