Expedited calibration for multiple accessors in library of portable data storage media

摘要

A portable data storage media library includes multiple accessors, various designated access sites, and multiple calibration locations having various spatial relationships to the access sites. Calibration of the accessors begins by determining positional relationships between different accessors to different of the predetermined calibration locations, and determining a positional interrelationship between different accessors to at least one the predetermined calibration locations in common. The positional interrelationships are utilized to establish a positional relationship between each accessor and calibration locations for which the positional relationship has not been determined.
