ABSTRACT:
An information recording medium comprising a hygroscopic swelling layer having the hygroscopic swelling property formed on a recording layer. Also the hygroscopic swelling layer is hygroscopically swollen with the hygroscopic swelling of the substrate, so that the tilt (i.e. warping) of the information recording medium is suppressed as a whole, whereby the quantity of the tilted deformation due to the moisture absorption is reduced. As a result, the recording and regeneration of information are stably conducted even though the humidity is changed.
