INFORMATION RECORDING/REPRODUCING DEVICE

摘要

This invention provides an information recording/reproducing device characterized by comprising a recording layer, a voltage application part, an electrode layer for applying voltage to the recording layer, and an alignment control layer, the recording layer comprising a first layer containing a first compound, which is a composite compound containing at least two cation elements, at least one of the cation elements being a transition element having a d orbit incompletely filled with electrons, the smallest distance between adjacent cation elements being not more than 0.32 nm, the voltage application part being adapted for applying voltage to the recording layer to cause a phase change in the recording layer to record information, the alignment control layer being provided between the recording layer and the electrode layer for regulating the alignment of the recording layer.
