1.   A junction consists of two magnetic layers separated by an insulator.

2.   But this makes it inefficient for recording analogue signals, which require a thick magnetic layer to capture low frequencies.

3.   Kodak and Fuji coated the film with a magnetic layer that tells a computer in the developing lab to makes adjustments to the color and lighting.

4.   The film is coated with a magnetic layer which transfers information about the photo to a computer in the developing lab.

5.   The magnetic field of one magnetic layer always remains in one particular direction, the field in the other layer can be switched back and forth.

6.   To improve picture quality, the film is coated with a magnetic layer that transfers information about the photo directly to a computer in the developing lab.

7.   The new type of intelligent film has a magnetic layer that allows cameras, film and photofinishing equipment to communicate with one another.
