Preserving the Past is a Forlorn Task

Commentary2.jpgThis week I presented a webinar on how to protect your stuff using archiving. Why? Because hard disks are great for immediate storage, but inadequate for files that you want to keep for a long time.

Hard disks will reliably store data with the power off and stored on a shelf up to about five years. DVDs last about seven years. Flash drives last about eight years. (Source: mDisc). In other words, the tools we use to store media for immediate use are not the tools we want to use to store media for the long term.

The purpose of my webinar was to show how to use LTO (Linear Tape – Open Technology) tape for long-term archiving. (And even with LTO, the phrase “long-term archiving,” is somewhat misleading, as you’ll read shortly.)

NOTE: You can download my webinar here and I encourage you to do so.

One of the questions that came up during the session was “What about mDisc? Why not use them for archiving?” This is a great question that speaks to a much larger issue that I wanted to talk about today.


mDisc replaces the traditional organic substrate in either a DVD or Blu-ray Disc with an inorganic substance. Because of this simple change, media stored on an mDisc, according to the mDisc website, can last up to 1,000 years. Even allowing for excessive marketing hype and discounting it by 75%, this means mDiscs will last hundreds of years.

I’ve had the chance to talk with the mDisc folks on several occasions and think they have a great idea and are working hard to share it with the world. My problem with mDisc isn’t their technology, but the technology industry.


Technology, as an industry, acts like the past doesn’t exist. As we have seen far too many times in the past, whenever a new idea can do a task better, even if it is incompatible with what has gone before, the new idea wins; even if it is as simple as changing connectors.

My office is littered with the dead-ends of storage technology:

  • Floppy disks – in all manner of sizes
  • SCSI hard drives
  • SyQuest drives
  • Jaz drives
  • FireWire 400/800 drives

Or, if you need something more dramatic, look at the industry bombshell that exploded four and a half years ago with the release of Final Cut Pro X without the ability to update files from Final Cut Pro 7. The reverberations from that shock are still playing out in our industry today.

NOTE: In response to this firestorm, Apple worked with independent developers to create upgrade tools which are now widely available through the Mac App Store.

Or, if you want a media example, look at film over the last 100 years as we’ve struggled with:

  • Various frame rates; including hand-cranked cameras
  • Various frame sizes
  • Various film stocks from nitrates to safety stock
  • Colors fading at different rates
  • Non-standard aspect ratios

Not to mention the myriad methods we’ve used to create special effects.

As media professionals, our job is to create media projects today, then preserve them for the future. The job of technology is to invent the future, without regard to what’s happened in the past.

These two missions are in conflict more often than not.


Which brings me back to mDisc. mDisc has what seems to be solid technology built around the hardware of the past – DVD and Blu-ray Disc. And both these hardware boxes are becoming increasingly difficult to find.

Both Apple and Adobe have discontinued their DVD and Blu-ray authoring programs. (The ability to create DVD or Blu-ray material inside Final Cut, Compressor, or Premiere is extremely limited.) Protestations from Sony not withstanding, Blu-ray Discs have never achieved the market success of DVDs.

To the best of my knowledge, no currently shipping computer (as opposed to used or refurbished units) ships with a DVD drive. If it wasn’t for XDCAM, Blu-ray Discs would be virtually invisible.

mDisc is limited, not by its technology, but by the tech industries infatuation with the simplicity of downloads at the expense of optical media. Anyone whose business relies on selling DVDs – the wedding video industry comes first to mind – knows that the optical media market isn’t dead. But it died long ago from the tech industry’s point-of-view.

Its my guess that within five years we won’t find any optical media hardware available in the market. At which point, what good is a disc that can last for 1,000 years, if we don’t have a way to play it back?

When it comes to tech, the past is an annoyance.

LTO ISN’T MUCH BETTER… (continued)
