In an optical recording medium, even when a plurality of recording and reading layers are stacked, deterioration in the recording and reading signal quality thereof is suppressed. Furthermore, the transfer rate thereof can be increased. When recording or reading information by means of light irradiation on or from an optical recording medium having a plurality of recording and reading layers which are stacked in advance or formed eventually, an optical recording and reading device includes: a first optical system for irradiating a first beam to recording and reading layers to be a first target to perform recording or reading of information; and a second optical system for irradiating a second beam to recording and reading layers to be a second target to perform recording or reading of information.
