A process which is performed by a recording/reproducing device configured to irradiate an optical recording medium including a plurality of recording layers with laser light to record and reproduce data, and is for determining at least one of a recording condition at the time of recording user data on any one recording object recording layer of the plurality of recording layers, or a reproducing condition at the time of reproducing the data from the recording object recording layer, where record management data indicating a recorded area on the recording layers is recorded on the optical recording medium. The process includes: acquiring a remaining capacity of a test recording area for each of the recording layers based on the record management data; and determining a recording layer on which test recording is intended to be made based on the remaining capacities of the test recording area acquired for the recording layers.
