摘要：
According to one embodiment, a single-sided, multilayered optical disc which performs recording and playback when irradiated with a laser beam having a predetermined wavelength, and has at least two recording layers that are independent of each other with respect to the light incident surface, a reflecting layer farthest from the light incident surface contains an Ag alloy, and has a light absorbance of 20% (inclusive) to 50% (inclusive) to a laser beam and/or a thermal conductivity of 50 (inclusive) to 250 (inclusive) W/m·K.
