Abstract
In an information recording medium, there is a tendency that unevenness in the number of times of access is liable to be generated between an area frequently accessed and an area not frequently accessed, so that a fault such as a write error, a read error, or the like is liable to occur due to physical degradation with time or the like resulting from frequent access to a specific area. Therefore, the numbers of times of recording of respective areas are managed to avoid nonuniformity of the numbers of times.
