  • Film data recording/reproducing apparatus for a camera by writing/reading pits recorded on a film
    Patent number: 5532774
    Abstract: A thermal head records data on a photographing film in the form of fine pits formed on the surface of the photographing film by its fine heating sections tightly contacted to the photographing film while the photographing film is being moved in a camera. A data detecting optical system projects light on the pits representing data on the surface of the photographing film and receives the light reflected by the photographing film. A line sensor detects rays of light scattered by the pits when the photographing film reflects the projected light, thereby reading out the recorded data.
