For Preservation Week (April 27th - May 3rd), it’s fun to share some of the unusual media formats you might find in the Archives that we preserve alongside our many paper and digital records. Archives are entrusted with preserving a large variety of records and some media can be more challenging to preserve and make accessible due to the rapid changes in technology. Things can become outdated so quickly! Audiovisual records and early born-digital computer files can be difficult to play back as this media can be very fragile. We may not have a functioning playback machine to hear or see the records. Archivists provide access for future generations by keeping one foot in the past. One of those preservation challenges here at the County Archives were dictation records on blue vinyl recordings called Audographs.
An Audograph was a dictation disc format introduced in 1946 by the Gray Manufacturing Company in the US. They were thin plastic discs, recorded from the inside to the outside, the opposite of conventional phongraph discs. Unlike a phongraph discs, the Audograph was driven by a surface-mounted wheel, meaning that its recording and playback speed decreased toward the edge of the disc (like the Compact Disc and other digital formats), to keep a more constant linear velocity and to improve playing time. Audograph discs were available in three different sizes.
At the County Archives, we used a record player with digital output to play the vinyl discs from the Board of County Commissioners records (multco008) at 33 rpms, and using a media player slowed the speed to sound more like normal human speech. Now it was possible to digitize these recordings and provide access.
If you want to learn more about different types of old formats you can go to https://obsoletemedia.org/obsolescence-decade/ where I got some additional information about Audographs for this post.
If you have questions about preserving your family records, we can help! Feel free to contact us via email at [email protected]. We can give you some preservation advice, or point you in the right direction.
Preservation week was started by the American Library Association’s Core (ALA) team. Preservation Week inspires action to preserve personal, family, and community collections in addition to library, museum, and archive collections.
