The Dead-Media Bogeyman

Most of today's long-term computer users have experienced dead media in the form of the 5.25-inch floppy disk.

Most of todays long-term computer users have experienced dead media in the form of the 5.25-inch floppy disk. If you have an old disk to read, you probably no longer have a computer equipped to read it; the 5.25-inch drives are becoming collectible. But if you have one, you should know that a lot of plastic and rubber parts fail. Tape backup is worse. I have a number of backups on nonstandard tape that are useless, their data essentially lost forever.

Dead-media issues are not confined to digital computers. For example, most of the vintage 1960s quad-head video gear for recording TV no longer works. The few big Ampex monsters that are left are being used to transfer old tapes onto a different format while they still can. There probably will not be enough time to move everything over, and plenty of quad tapes will remain in storage and become useless.

This brings us to the issue of digital photography and all the pictures we are taking. Will they end up on dead media and be lost forever? Probably not—and perhaps the opposite will happen. As anyone who has adopted digital photography knows, you end up with too many backup copies of your images. With digital imaging, we take more pictures and have more perfect copies than ever. During the film era you had one lone negative, and it was often scratched.

More images were lost because of scratched or lost negatives—which could never be perfectly backed up—than you lose today as a result of format changes. If the negatives or pictures got wet, they were ruined. The really old stuff, from the turn of the previous century, has faded for good, and there are no digital negatives to save it. Computers can sometimes pump the colors of old negatives to get close to what they once were, but old color negatives are fading faster than we can fix them.

That said, there has to be some concern over the long-term reliability of digital storage, with the recent overblown fears about disc rot—a perceived problem that harks back to the late 1970s and some bad pressings of laserdiscs. In fact, we are witnessing a consolidation process resulting in more and more backups. And because we tend to use music industry–type (CD and DVD) consumer standards, we will probably have playability for a hundred years or longer. There is not as much dead media in the music industry; just consider that with the right equipment you can still play a 78-rpm record from 1904!
