ABSTRACT:
An information memory and display medium comprising: (a) a support, (b) a magnetic recording layer formed on the support, (c) a thermosensitive recording layer formed on the magnetic recording layer, which comprises (i) a light reflection layer formed on the magnetic recording layer, and (ii) a reversible thermosensitive recording layer formed on the light reflection layer, comprising a matrix resin, and one or more organic low-molecular-weight compounds dispersed in the matrix resin, with the transparency thereof being reversibly changeable between a transparent state and an opaque state depending upon the temperature thereof, thereby capable of yielding thermally erasable images. The thermosensitive recording layer may further comprise a smoothing layer between the magnetic recording layer and the light reflection layer, and/or an overcoat layer on the reversible thermosensitive recording layer.
