摘要： A one-side incident type optical recording medium having a plurality of recording layers capable of instantaneously switching recording/reproduction conditions (such as the tracking polarity, the recording pulse strategy, and the advisable recording power) according to each recording layer and accurately and surely executing information recording or reproduction on the recording/reproduction condition according to each recording layer. In each of the plurality of recording layers of the optical recording medium, information can be recorded or reproduced by radiation of a laser beam from one side. A control section reads out layer information from one of the recording layers, each having layer information recorded (layer information read out step) and controls so that recording or reproduction is performed on the recording/reproduction condition in accordance with the recording layer specified by the layer information (recording control step).
