ABSTRACT:
A defect entry, including position information of a defective block of a reference information layer and state information indicating the defective state of blocks of the other information layers located adjacent to a perpendicular direction at a position of the defective block of the reference information layer, is recorded on a holographic information storage medium. A method of inspecting for a defect includes determining whether blocks in a reference information layer are defective, and determining whether blocks of the other information layers located adjacent to a perpendicular direction at a position of a defective block of the reference information layer are defective, based on a result of the defect determination of the reference information layer.
