摘要:
An optical recording medium for a land & groove recording method capable of suppressing crosstalk and cross-erase (increase of jitter) upon increasing the capacity by the increase of track density, wherein a depth for a groove is made greater than 60 nm, at least one of a protection layer, a recording layer and an interference layer is formed to a layer thickness different between the groove and the land, such that reflectance to an optical beam upon irradiation of the optical beam to a predetermined track comprising the land or the groove is equal with each other between a portion in a recorded state and a portion in a unrecorded state of an adjacent track adjacent with the predetermined track, and a land wall for one of the protection layer, the recording layer and the interference layer is made thinner than the thickness of the groove and the land or removed.
