PURPOSE:To use a recording stylus itself for impressing an electric field and irradiation of a light for heating upon a recording layer so as to simplify the constitution of a high-density recording device, by passing the laser light for heating through the recording stylus itself equipped with an electrode and heating the recording layer of a recording medium with the laser light. CONSTITUTION:An electrode 4 is constituted at the front end section of an optical fiber 3, to which a laser light is supplied from a light source, by a means which deposits a conductive material, etc. An information signal voltage is supplied to the electrode 4 from a recording signal source through a connecting line 5 and a cantilever 6 coupled with a carrying device is fixed to the optical fiber 3 near the front end section. When the laser light is passed through the optical fiber 3 and an information signal voltage is applied upon the electrode 4 through the connecting line 5 by using the recording stylus constituted in such a way, a phase change occurs in the recording layer 1 of a recording medium D and information signals are recorded. |
