Slack sensor for a storage library

Номер: US20130248297A1
Автор: Daniel James Plutt, Joseph Paul Manes
Принадлежит: Oracle International Corp

Systems and methods are described for providing sensing slack on cabling coupled between a drive mechanism and a carriage. Embodiments of the carriage are configured so that the cables are substantially in tension when Z-directional movement of the carriage is substantially unimpeded and at least one cable manifests slack when Z-directional movement is impeded. Accordingly, detecting slack on the cables can be used to detect impedance to Z-directional movement of the carriage. According to some embodiments, a novel slack sensor translates tension on the cables into a forward pulling force that holds the slack sensor in a deactivated state. A reverse force is maintained on the slack sensor in a magnitude and direction that causes the slack sensor to move to an activated state whenever sufficient tension is not manifest on the cables. Slack can thus be detected by detecting when the slack sensor is in its activated state.

A library control device moves a desired record medium from a magazine, which is configured to load a plurality of record media into a plurality of slots, to a drive so as to read or write data. The library control device stores identifications of record media in correlation with slots loading recording media. Upon detecting a malfunction in reading or writing data with a record medium, an operator needs to extract the record medium from the magazine. At this time, the library control device rewrites the identification of a slot, which is stored in correlation with the record medium subjected to extraction, with the identification of a predetermined slot so as to move the record medium to the predetermined slot. Thus, it is possible for an operator to extract the record medium detecting a malfunction from the predetermined slot without making any mistake. 1.
