ABSTRACT:
Disclosed is a magnetic recording element comprising a support having coated on at least one major surface thereof a layer of a magnetic recording medium and a photosensitive layer which may be separate from or integral with the magnetic recording layer and which contains an infrared absorbing dye or its precursors. Information can be imparted to the photosensitive layer by imagewise exposure to actinic radiation which will either promote or inhibit generation or destruction of the infrared absorbing dye.
