In this case, the component ratio of Te and Se is selected not to be excess for other elements, such as Ge, Sb/or Bi so as to be fixed as stable compounds of stoichiometric compositions of GeTe, Sb.sub.2 Te.sub.3 /or Bi.sub.2 Te.sub.3, or GeSe, Sb.sub.2 Se.sub.3 /Bi.sub.2 Se.sub.3 when crystallized.

摘要： An information device is an information device that records information on or reproduces information from an information recording medium (3). The information device includes a light source (14) and a near-field light generating element (9) including a resonating section (22) configured such that plasmon resonance occurs between the resonating section (22) and a recording region (4). The resonating section (22) causes the plasmon resonance when emission light from the light source is irradiated on the near-field light generating element (9). A resonance enhancing film enhances the plasmon resonance between the resonating section (22) and the recording region (4). The resonating section (22) generates near-field light and irradiates the near-field light on the recording region (4) from a recording layer side.
