Recording/reproducing device and optical disk library device

An optical disk library device for carrying a plurality of optical disks and recording and reproducing information on the optical disks, the device comprising:

• a recording/reproducing device that records and reproduces information on the optical disk;
• and
• a library controller that transmits and receives information to/from the host controller connected to the library device,
• wherein the recording/reproducing device reproduces an area recorded on the optical disk, and includes a recording quality storage part for storing quality information showing a recording state of the area, and when data to be recorded on the optical disk is transmitted to the recording/reproducing device from the host controller via the library controller, the recording/reproducing device records the transmitted data on the optical disk,
• wherein the recording/reproducing device transmits reproduced data to the host controller via the library controller while storing the quality information at the time of reproduction in the recording quality storage part by a first instruction from the host controller, and transmits the quality information stored in the recording quality storage part to the library controller by a second instruction from the library controller,
• wherein the library controller includes a recording quality determination part for determining the quality information, and
• wherein the recording quality determination part of the library controller determines the quality information transmitted from the recording/reproducing device, and when it is judged that the recording quality has not reached a previously decided criterion, transmits a quality information determination result to the host controller.
