ABSTRACT:
In an information reproducing method, directory data for managing file data is recorded on an information recording medium to manage recording reproduction of the file data. There are provided a defect bit map in which defect information indicating if a defect exists or not corresponding to each physical address of the recording medium is recorded on the recording medium, and a defect index table on which the number of defects in a block is recorded every predetermined block of the defect bit map. When a designated logical address is converted into a physical address, searching is sequentially performed on a block on the defect index table where the designated logical address exists and a physical address in the searched block on the defect bit map.
