摘要：
To provide a recording method and a storage medium for BCA data with high reliability for a storage medium and a method for reproducing BCA data from the storage medium, and an information recording apparatus and an information reproducing apparatus. In a conventional optical disk, low reliability data is recorded in a data area of BCA. Thus, the thickness of a film material for use in a recording layer oriented to BCA data or close to the inner periphery of the storage medium in the vicinity thereof is formed in uniform thickness by using a substrate of the storage medium, the substrate being formed by being suctioned by means of adsorbing mechanisms (56, 71, 72) formed in an arc shape so as to integrated two of the adsorbing mechanisms to be adjacent to each other. Therefore, the information recorded in a BCA (burst cutting area) or recorded close to the inner periphery of the storage medium in the vicinity thereof can be recorded precisely and stably.
