A conventional checking methodin 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 magazinetakes 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.

In one embodiment, an apparatus includes an accessor configured to transport data storage cartridges in a library environment, and a bracket configured to receive a wireless image capture device therein where the bracket is positioned to orient the wireless image capture device to capture images while the accessor is transporting data storage cartridges. In another embodiment, a method for mounting a wireless capture device to an accessor to capture images of an operation in a data storage library includes mounting a bracket to the accessor, where the accessor is configured to transport data storage cartridges in a library environment, where the bracket is configured to receive a wireless image capture device therein. The bracket is mounted in a position to orient the wireless image capture device to capture images while the accessor is transporting data storage cartridges.
