PROBLEM TO BE SOLVED: To provide a nonvolatile information recording and reproducing device having high recording density and low power consumption. SOLUTION: The information recording and reproducing device is provided with a recording layer and a means for recording information by causing phase transition on the recording layer by applying voltage to the recording layer. The recording layer is constituted so as to include a first compound having spinel structure expressed by at least chemical formula 1:A<SB>X</SB>M<SB>Y</SB>X<SB>4</SB>(0.1≤x≤2.2, 1.5≤y≤2). Here, A is at least on kind of element selected from a group of Zn, Cd, Hg; M is at least one kind of transition element selected from a group of Cr, Mo, W, Mn, Re; and X is O.
