Abstract
Photographic film is provided with a magnetic recording layer applied to at least one edge surface thereof in the longitudinal direction of the film and substantially over the entire thickness thereof. A magnetic head of a recording-reproducing system is positioned upon recording or reproduction so that a magnetic field is established in the direction of thickness of the film or the direction of width of the magnetic recording layer.
Claims1
A method of magnetic recording on photographic film having a magnetic recording layer coated on an edge surface of the film in the longitudinal direction thereof and magnetic reproduction from the same characterized in that a magnetic head is positioned with respect to said edge surface of the film so as to establish a magnetic field in the direction of thickness of the film upon recording and so as to read a magnetic field in the direction of thickness of the film upon reproduction, with the magnetic head being kept spaced from the film, thereby accomplishing Y-direction recording or reproduction.
