Abstract

An information recording medium comprising a stack of layers includes a recording layer interposed between two shielding layers, the shielding layers being opaque to radiation within a predetermined waveband. The recording layer is adjacent to a layer which is transparent to radiation within the predetermined waveband, and is readable by radiation within the predetermined waveband passing into the layer through a free edge of the layer.
