A stack "0" having a recording layer serving to transmit a light beam includes a heat dissipating layer, a reflective layer, an enhanced layer, and the recording layer, which are formed in that order on an intermediate layer. The reflective layer is translucent to a light beam, while the heat dissipating layer has a thermal conductivity higher than that of the intermediate layer as well as a refractive index higher than or equal to that of the intermediate layer and less than or equal to a refractive index 3. The thickness of the heat dissipating layer is set to a value within the range of a predetermined condition defined in accordance with a refractive index, the wavelength of the light beam, and a given integer. Thus, an information read/write medium configured to enable information to be recorded/reproduced thereon/therefrom as well as to effectively cool a recording layer serving to transmit a light beam is provided.
