摘要： An information recording apparatus is provided with a recording controller for recording data on an information recording medium, a verification controller for verifying whether or not the recorded data can be correctly reproduced, a continuous recording controller for providing a gap region of a specified interval between a verification region and a recording region and successively performing a verify processing and a record processing with rotation waiting in between, an error region discriminator for discriminating an error region in the event of an error in the process of performing the verify processing and the record processing, and an error processor for performing an error processing according to the error region. The error processor performs an error processing different from the one performed when an error occurred in either one of the verification region and the recording region if an error is discriminated to have occurred in the gap region. By this construction, a recording time is shortened and it is prevented that data cannot be recorded on the information recording medium.

摘要： Provided is an information recording/reproduction apparatus including: a recording request receiving unit for receiving a recording request for recording information on an information recording medium including two or more recording layers; and a recording unit for recording the information by, limiting the number of recording layers including an area with information recorded thereon to a predetermined value N (N≧0) or less with respect to other recording layers in which the light passes therethrough until light reaches an unrecorded area of a recording layer as a recording target. According to this configuration, it is possible to guarantee the recording quality of a multilayered information recording medium.

摘要： A control apparatus is provided for controlling an access means for accessing a recording medium containing at least one area so that the access means accesses the at least one area. The apparatus comprises a means for determining whether or not at least one first recorded area storing data is included in the at least one area, and a means for controlling the access means. When it is determined that the at least one first recorded area is included in the at least one area, the control means controls the access means based on a result of accessing the at least one first recorded area.

摘要： In an information recording medium in which storage capacity per recording layer has increased so much that the size of an SBM varies with those of spare areas, there is mutual dependence between a DDS and an SBM and it is difficult to retrieve disc management information as intended. In an information recording medium according to the present invention, if the largest space is allocated to an user data area, the number of blocks to store a space bitmap is Ni (where Ni≧2). But if the smallest space is allocated to the user data area, the number of blocks to use is smaller than Ni. In such an information recording medium, if the number of blocks to store the space bitmap of a recording layer is Mi (where 1≦Mi≦Ni) and if Mi is equal to or greater than two, the space bitmap is divided into the 1st through Mith space bitmaps, each of which has a size that is still equal to or smaller than one block even when combined with a DDS, and each space bitmap is stored in an associated one of Mi blocks in a disc management area.
