PROBLEM TO BE SOLVED: To solve such a problem that a marker formed on a disk position of a disk storage cartridge by a sensor attached to a conveyance device for conveying each disk, but even when a marker position is accurately detected, the disk position cannot be accurately detected due to a positional deviation between the disk position and the marker position, separation of an attachment position of the sensor from a disk inserting/ejecting mechanism or the like and a disk conveyance error may be generated.SOLUTION: An optical disk library apparatus including a cartridge capable of storing disks and having markers formed on respective disk storage positions, a disk conveyance device for conveying each disk to a drive and a first sensor arranged on the conveyance device side to read out each marker further includes a second sensor for detecting the disk, so that a desired disk can be accurately extracted. |
