1. A method for implementing autonomous variation of media dismount time in a robotic media library comprising the steps of:
monitoring input/output (I/O) requests to the robotic media library and maintaining an I/O operations count,
gathering performance statistics for said I/O requests to the robotic media library;
periodically checking said gathered performance statistics to determine said change value needed for the media dismount time including identifying a first threshold number of I/O requests, and checking said gathered performance statistics to determine if an increase is needed for the media dismount time.
