Optical disk having super-resolution film

摘要

An optical disk from which recorded data are read out by means of light irradiation has a substrate (12) having recording pits as data on a surface thereof, and stacked films formed on the substrate (12). The stacked films contain a super-resolution film (13) of a polymer matrix and semiconductor particles having an organic group covalently bonded thereto, and a reflective film (14) reflecting light. The super-resolution film (13) and the reflective film (14) are provided in this order from a light incident side.
