摘要： 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.

摘要： The present invention is to realize a proper inner zone layout in a quadruple-layer disk.A test area is provided in the inner zone (inner circumference side area) in each of recording layers. If two test areas closer to the outer circumference, of four test areas, are defined as a first pair and two test areas closer to the inner circumference are defined as a second pair, the test areas of the first pair and the test areas of the second pair are so disposed as to be prevented from overlapping with each other in the layer direction. Two test areas of the first pair have the same consumption direction of the test area, and are so disposed that the areas to be used next hardly overlap with each other in the layer direction. Two test areas of the second pair have the same consumption direction of the test area opposite to the consumption direction of the test area in the first pair, and are so disposed that the areas to be used next hardly overlap with each other in the layer direction.
