Abstract
A method of recording data in a multilayered recordable optical recording medium is disclosed. When test recording is executed in a multilayered recordable optical recording medium having N recording layers (N is an integer of 2 or more), a test recording range in a test recording area of an (m+1)th recording layer is shifted relative to a test recording range in a test recording area of an mth recording layer by an amount greater than a difference of decentration amounts between the mth and the (m+1)th recording layers or a maximum decentration amount in the N recording layers. The shifting direction is inverse to a test recording range adding direction in a radius direction of the recording medium.
