ABSTRACT:
A method of recording information on a thin film of thermoplastics material over a generally circular recording area, comprises the steps of directing a focussed, modulated beam of electrons on the film and simultaneously moving the film so that the beam deposits a track of charge which follows a spiral path, the film being carried by a support which has a conductive part in contact with the film, wherein the film is heated by the passage of an electric current through the conductive part of the support, the current being circumferentially uniform over the recording area. Preferably the information is recorded over an annular recording area between two spaced concentric conductive annular members in contact with the conductive part of the support, between which members the current is passed.
A support for use with the method may comprise a conductive plate of which the local resistance per unit surface area at any point within a substantial part of the plate is proportional to the square of the radius of that point from the center of the plate.
