How did Voyager 1 send back images of earth? Film or digital?! lt always bothers me

I'm not suggesting it ejected a film c canister back to earth....but how did it convert an image to signal and then transmit it?

The Voyager spacecraft were equipped with Vidicon cameras. These cameras operated by scanning a photosensitive plate with a cathode ray tube and recording the differences in charge density. This is an analog technology, but the images could be stored on the spacecraft's tape memory and transmitted by radio.
