摘要： An apparatus according to the present invention is designed to perform formatting processing on an information storage medium. The storage medium has a data storage area including a user data area and a spare area. The user data area is provided to write user data on, while the spare area includes a replacement block to be used as a replacement for a block that has been detected as a defective block. The replacement block stores instruction information that instructs to read data from the defective block when data is read from the replacement block. The apparatus includes a control section for controlling the formatting processing. In performing the formatting processing, the control section updates information stored in the replacement block such that when data is read from the replacement block, the data is not read from the defective block.

摘要： An additionally recordable information recording medium has a complicated management structure for managing an unrecorded area. Therefore, there are problems that it takes a long time for a disk to startup and it is difficult to build a recording/reproducing system. The additionally recordable information recording medium according to the present invention includes a simple data structure for managing a location information for a recorded area located at the rearmost location in a user data area. An additionally recordable apparatus according to the present invention also includes means for updating the location information of the recorded area so that the recorded area located at the rearmost location in the user data area is always managed.

摘要： On a recording medium, data is recorded on at least one of a plurality of recording layers by laser light incident on a surface of the recording medium. The plurality of recording layers include a first recording layer, and second through N-th recording layers (N is an integer of 3 or greater) which are sequentially located in a direction from the first recording layer toward the surface on which the laser is incident. The plurality of recording layers each have a first calibration area and a second calibration area located outer to the first calibration area. The first calibration area located in each of the first through N-th recording layers is located at a different radial position from a radial position of the first calibration area in each of the other recording layers; and the second calibration area located in each of the first through N-th recording layers is located at the same radial position as a radial position of the second calibration area in each of the other recording layers.
