摘要：
According to one embodiment, an information recording and reproducing device includes a first layer, a second layer, and a recording layer between the first and second layers, which is capable of a transition between a first state of a low resistance and a second state of a high resistance by flowing a current between the first and second layers. A peripheral portion of the recording layer has a composition different from that of a center portion of the recording layer. The center portion includes two kinds of cation elements. And the center portion is different from the peripheral portion in a ratio of the two kinds of cation elements.
