    摘要： An information recording medium comprises a user area, and a spare area including a replacement area, wherein the replacement area may be used instead of a defective area in the user area. The user area and the spare area include a plurality of sectors. Each of the plurality of sectors includes a user data area for recording user data, and an attribute data area for recording defect replacement allowance attribute data. The defect replacement allowance attribute data indicates whether recording of the user data has been executed in a state that the execution of a defect replacement process is allowed. In the defect replacement process, the defective area in the user area is replaced with the replacement area in the spare area.

    摘要： An information recording apparatus 110 includes a defect list update section 122 for updating a defect list having a defect address registered therein which represents a position of a defect area existing in a user area, and a recording section 113 for recording information on the information recording medium 130 based on the updated defect list. The defect list update section 122 determines whether or not an area designated by the defect address registered in the defect list is a defect area; and when the area designated by the defect address is determined not to be a defect area, the defect list update section 122 deletes the defect address, registered in the defect list, from the defect list.

    摘要： A recording method for an optical disc drive and an optical disc drive capable of preventing a light source of a laser beam or a laser driving portion from becoming uncontrollable as they are heated to high temperatures above their compensation temperatures, and thereby enabling recording to be continued in a stable manner without being interrupted or stopped until it ends. A surrounding temperature is measured by a temperature sensor serving as temperature measuring device, a set surrounding temperature is correlated with a set recording rate by using a data table stored in an internal memory of a controller serving as correlating device, and a recording rate is changed by a digital signal processing portion serving as recording control device on the basis of the surrounding temperature measuring result and the correlating result, wherein the recording rate is changed by changing a ratio of a recording operation time and a recording-stop operation time with alternately repeating a recording operation and a recording-stop operation at as low a laser beam output as playback.
