Zusammenfassung:According to one embodiment, an information recording and reproducing device includes a first layer, a second layer and a recording layer. The recording layer is provided between the first layer and the second layer and being capable of reversibly changing between a first state having a first resistance and a second state having a second resistance higher than the first resistance. The recording layer includes a first compound layer and a second compound layer. The first compound layer contains a first compound. The first compound includes a first cation element and a second cation element of a type different from the first cation element. The second compound layer contains a second compound. The second compound includes a transition element having a d-orbital partially filled with electron, and the second compound includes a void site capable of storing at least one of the first cation element and the second cation element.
