Abstract
The present invention relates to a library system including a disc recording/reproducing unit, a disc container, and a disc transport unit for transporting a disc between the disc recording/reproducing unit and the disc container. In order to improve the reliability of the operation of moving the disc from the disc recording/reproducing unit to the disc transport unit, a disc transport controller determines the situation in both the disc recording/reproducing unit and the disc transport unit, and error-stops the operation according to the result of the determination. Alternatively, the disc transport controller retries the movement of the disc, by pulling the disc into the disc transport unit or returning the disc to the disc recording/reproducing unit, and by finely adjusting the relative positions of the disc recording/reproducing unit and the disc transport unit if necessary, in order to solve the problem of damage to a surface of the disc.
