The present invention provides an optical recording material allows for obtaining excellent recording signal properties even at high-speed recording and is excellent in durability in both a single-sided single layer optical recording medium and a single-sided two-layer optical recording medium having a first recording layer and a second recording layer. The optical recording material contains a cyanine compound having a specific structure and a squarylium compound as dyes for optical recording layers.

Optical recording material, optical recording medium, and recording and reproducing method of optical recording medium

A photoelectric conversion element includes a plurality of light receiving portions. A color filter is provided on a light receiving surface of the photoelectric conversion element with filters for red, green, and blue arranged corresponding to the light receiving portions, such that R, G, and B pixels including the light receiving portions and the filters are arranged in a two-dimensional array. A transfer unit transfers a light in a wavelength range other than lights of green and blue incident on the G pixel and a light in a wavelength range other than lights of blue and green incident on the B pixel to a neighboring R pixel.
