Track anomaly detection in an automated data storage library
First Claim
Patent Images
1. A method of detecting track anomalies in an automated storage library having at least one robotic device servicing data storage requests, the method comprising:
- forming a track having a first end and a second end, at least one robotic device operative to access data storage devices by moving along the track;
transmitting a track health signal from the first end of the track section; and
determining the presence of a track anomaly based on any reception of the transmitted signal at the second end of the track.

Abstract
Track anomalies in an automated storage library are detected by transmitting a track health signal from one portion of the track. The presence of a track anomaly is determined based on any reception of the transmitted signal at another portion of the track.

11. A data storage library comprising:
-
a plurality of storage locations for holding data storage media disposed within the library;
a rail disposed within the library located to provide access to the storage locations;
a conductor on the rail;
at least one robotic device mounted to travel along the rail, the robotic device accessing storage media held in the storage locations;
a transmitter in communication with the conductor, the transmitter operative to transmit a track health signal onto the conductor; and
a receiver in communication with the conductor, the receiver operative to receive the track health signal and to determine track health based on the transmitted track health signal. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21)

22. A method of determining the health of track used in an automated storage library having at least one robotic device servicing data storage requests by moving along the track, the method comprising:
-
transmitting a track health signal through a conductor, the conductor following the track, the conductor supplying electrical current for operation of the at least one robotic device;
sensing presence of the track health signal on the conductor; and
determining track health based on the transmitted track health signal and on the sensed presence of the track health signal.
