    Abstract: An optical recording medium having two or more information recording layers in which information is recorded at high recording density. The incidence of light on the information recording layer disposed far from the top layer through which light enters and the returning light from the information recording layer can be detected at high efficiency. The recording/reproducing characteristics are favorable. An optical recording/reproducing method for at least reproducing/recording information from/on this optical recording medium is also disclosed. The optical recording medium (10) comprises information recording layers (21, 22) between a first major surface on which light can be incident and a second major surface opposed to the first major surface. The first information recording layer (21) nearest to the second major surface is a phase-modulation information recording layer, and the second information recording layer (22) is a reflectance-modulation information recording layer. Information is reproduced or recorded from or in the first information recording medium (21) of the optical recording medium (10) by a phase modulation method, and information is reproduced or recorded from or in the second information recording layer (22) by a reflectance modulation method.

    Abstract: PROBLEM TO BE SOLVED: To correctly reproduce information to be essentially recorded.SOLUTION: In an optical information reproducing device, a detection signal S obtained on the basis of a reflected light beam from an optical information recording medium is compared with a first signal level V1 and a second signal level V2 by a fluctuation detection part of a signal processing part to generate a first detection signal SV1 and a second detection signal SV2. In the signal processing part, the first detection signal SV1 and the second detection signal SV2 are converted into a first code sequence CV1 and a second code sequence CV2, respectively, by a code sequence generating part and when the second code sequence CV2 becomes a value 1, a substitution code sequence CR is substituted for a code sequence CB in the vicinity of the first code sequence CV1 to form a code sequence C. Thereby, in the optical information reproducing device, the code sequence C corresponding to two recording marks which should be essentially recorded can be generated even when merged recording marks are formed in the optical information recording medium.
