Abstract
There is provided a recording medium, a recording apparatus, a recording method, a reproducing apparatus, and a reproduction method that make it possible to correctly reproduce multilevel codes recorded at high density. A multilevel code of at least three ML values produced by coding user data into a (d,k)-RLL code of the ML values and a particular pattern of the ML values that includes a run of repeated codes which is greater than a maximum run k of the multilevel code are recorded on a recording medium. In addition, reproduction is performed from the recording medium, and the multilevel code is decoded according to the particular pattern. For example, the present technology can be applied to a recording medium, a recording/reproducing apparatus that performs recording on and reproduction from the recording medium, and the like.
