The invention provides a method for determing recording condition or reproducing condition. In a recording/reproducing device for recording and reproducing data by the irradiation of a laser beam in and from an optical recording medium with a record managing data recorded therein, which has a plurality of recording layers each having a test recording area and a user data area and which indicates the recorded area in the recording layers, provided is a method for determining at least one of a recording condition at the time of recording the user data in any recording object recording layer of the recording layers or a reproducing condition at the time of reproducing the data of the recording object recording layer. The determining method comprises acquiring the remaining capacity of the test recording area for each recording layer on the basis of the record managing data, determining a recording layer for a test record as a test recording layer on the basis of the remaining capacity of the test recording area
