ABSTRACT:
A thin film magnetic recording head and process for fabricating it is disclosed. The magnetic recording head has a core with a gap the same length as the width of an original document to be produced and is positioned in contact with a moving magnetic recording medium and perpendicular to the direction of movement thereof. A high magnetic permeable body is disposed in the gap of the head core and is in contact with the magnetic recording medium. A heat generation body of the same length as the high magnetic permeable body is positioned in contact therewith. Means for selectively heating segments of the heat generation body corresponding to the width of a picture element is provided. The portions of segments the high magnetic permeable body that are heated via the heat generation body segments, above its curie point are rendered non-magnetic forcing the magnetic flux generated in the core by an exciting coil external of this portion and into the magnetic recording medium, thus forming latent magnetic images in the recording medium.
