Library system

摘要

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.

主权项

1. A library system for storing a plurality of recording media to record and reproduce data, the library system comprising:
a disc container for storing a plurality of discs which are the recording media; an optical disc drive (ODD) configured to write and read information on the disc, and to detect a first movement error via a first detector; a disc transport unit configured to transport and exchange the disc by moving between the disc container and the ODD, and to detect a second movement error via a second detector; and a controller configured to control the operation of the ODD and the disc transport unit, to retry the operation of moving the disc based on both information about a state of the ODD and information about a state of the disc transport unit, responsive to the ODD detecting the first movement error or the disc transport unit detecting the second movement error in the operation of moving the disc loaded into the ODD to the disc transport unit.
