摘要：
An apparatus is provided for searching for a writable area of a write-once information recording medium, comprising a searching portion and a control portion. The searching portion searches for an unrecorded area using a prescribed address as a reference. The control portion provides a candidate address indicating a candidate for a writable area based on a result of the search, and performs a determination procedure for determining whether or not there is a defective area address indicating an address matching the candidate address in defect management information. When it is determined that there is not the defective area address indicating an address matching the candidate address, the control portion determines an area indicated by the candidate address as the writable area.
