Abstract
A method and apparatus are disclosed for recording information by deformation on a recording material having a photoconductive thermoplastic layer supported by a flexible transparent backing layer, characterized by the provision of electrostatic attraction means for stabilizing the recording material against lateral displacement during the continuous transport of the recording material through an exposure station. To this end, there are provided corona means for electrostatically charging the recording material prior to the transport thereof through the exposure station, and a stationary conductive layer of a given potential is arranged beneath the recording material opposite the charging and exposure stations, whereby the charged recording material is attracted to the conductive layer. A further conductive layer of given potential may be provided for stabilizing the charged recording medium during transport through a read-out station. Laterally flanged guide roller means are also provided for laterally stabilizing the recording material during transport between the supply and take-up reels.
