Re: [ARSCLIST] Storing Mini-Discs



Lou,

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 players.

Cheers,

Richard

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.

Good luck!

Richard
