Abstract: A conventional checking method—in which all of the optical disks are selected one by one from the plurality of optical disks stacked in a thickness direction and accommodated in a magazine—takes lots of time for checking. To solve the problem above, the optical disk device has a magazine, a disk drive, and a disk carrier device. The magazine accommodates a plurality of optical disks stacked in the thickness direction of the optical disks. The disk drive checks at least a recording surface facing an inner wall of the magazine of any optical disk of the optical disks accommodated in the magazine. Of the plurality of optical disks stacked and accommodated in the magazine, the disk carrier device takes out an optical disk positioned at an end in the thickness direction and whose recording surface faces the inner wall of the magazine, and carries it to the disk drive.

Abstract: On each of a plurality of recording layers of a write-once optical disc, two tracks constituted of adjacent land and groove are formed in a spiral shape. A writing method of data includes: a step of receiving data and a writing instruction of the data; and a step of recording management information, wherein the management information includes: virtual sequential recording range information that manages a last recorded address of the data as a virtual physical sector number; defect list that indicates a replacement correspondence relationship between the virtual physical sector number and an actually recorded physical sector number; and real next writable address information that indicates a real next writable address that is actually recordable subsequently to the physical sector number.

Abstract: An information recording method of recording information is provided in an information recording medium having a plurality of recording layers including a first recording layer and a second recording layer located to be closer to a surface than the first recording layer, each of the plurality of recording layers includes a user data area for recording user data, a spare area for alternatively recording data of failed recording into the user data area, and a management information area for recording management information. The first recording layer is used as a recording object layer at start of recording. When any one of the user data area, the spare area, and the management information area of the first recording layer runs short of a free space, then the recording object layer of the user data area, the spare area, and the management information area is switched over to the second recording layer.

Abstract: A distribution board includes: a pack housing unit which houses a battery pack and includes a connecting unit; and a charge control unit. The battery pack includes a connecting terminal unit for charge and discharge of power and can supply power to the distribution board and another device different from the distribution board. The connecting unit is connectable to and disconnectable from the connecting terminal unit. The charge control unit converts AC power supplied from a power system into DC power, and supplies the DC power to the battery pack housed in the pack housing unit to charge the battery pack.
