It’s a groove thing
I don’t want to downplay genuine discovery, but your story about optically reading old records left me a little underwhelmed (“Groovy Pictures: Extracting sound from images of old audio recordings,” SN: 5/29/04, p. 339: Groovy Pictures: Extracting sound from images of old audio recordings). The optical playing of records has been available in the commercial market for several years. Just do an Internet search for “laser turntables.”
