Data recording sheet

摘要

A data recording sheet in which data signals are stored in a polarizable macromolecular material sheet layer with polarization different locally in the direction of the surfaces of said sheet layer. The sheet layer causes pyroelectric or piezo-electric polarization through polarization operation, and the data signals thus stored are reproduced in a pyroelectric or piezo-electric mode. The polarizable macromolecular material sheet layer is laminated through a thin intermediate electrode layer on a macromolecular substrate layer whose Young's modulus is greater than that of the sheet layer.
