The optical retrieval and storage technique described in this paper provides a way for transferring sound information from an analog disk to a visual carrier avoiding any mechanical contact. The process is straightforward: we take a picture of each side of the disk using a dedicated analog camera, we store the film as our working copy and when needed, we scan the film and process the image in order to extract the sound.
