<p>Provided are an optical information recording medium and an optical information recording device that enable to accurately form recording marks each having a certain code length and to accurately reproduce information, even in the case where shingled write recording is applied to optical information recording. An optical information recording medium (1) is provided with a user area (102) configured such that optical characteristics of a photosensitive recording material are changed by irradiation of laser light for recording information. The user area (102) includes recording tracks (104) on which information is recorded by overwriting a part of recording marks (106), and a heat insulating area (105) which is concentrically or spirally formed, and insulates heat generated by irradiation of the laser light. The heat insulating area (105) is formed between the recording tracks (104).</p> |
