receiving a logical address to store new data from a host;
determining whether a first area with a physical address on the write-once information storage medium corresponding to the
logical address is occupied with data and, if the first area is occupied with data, determining the first area as a defective
area and recording the new data in a second area with a physical address different than the physical address of the first
area; and
recording updated defect management information, including the physical addresses of the first and second areas, in the write-once
information storage medium.
