Abstract: In an optical disc, a sector is sequentially formed with a first gap field, a first guard data recording field, a data recording field composed of synchronous signal and user data, a second guard data recording field, and a second gap field, wherein the length of the first and second gap fields, and the length of the first and second guard data recording fields is changed randomly in every recording, and the changing amount of the first and second guard data recording fields is set smaller than the changing amount of the first and second guard data recording fields, thereby suppressing optical disc medium deterioration in every sector and every mark resulting from repeated recording.

The information recording/reproducing apparatus has the capability of handling the information recording/reproducing media both when they are not in the case and when they are in the case. A recording mode is selected basing on the determinations of (i) whether or not the recording/reproducing medium is a medium type which is necessarily contained in a case at recording and (ii) whether the case is presence or absence. The recording mode is selected among (i) record information onto the information recording/reproducing medium, (ii) perform after-defect-inspection recording or defect-inspecting after recording, and (iii) inhibit recording of information.
