Data storage system.

摘要

A data storage system includes a recording-medium drive for driving one of a first recording medium and a second recording medium, a terminal device outputting access requirements, and a carrier mechanism for setting one of the first recording medium and the second recording medium into the recording-medium drive in response to an access requirement outputted from the terminal device. The system also includes a controller connected between the terminal device and the carrier mechanism for processing access requirements outputted from the terminal device to reduce a number of times of setting operation of the carrier mechanism. The controller includes a section for rearranging the access requirements outputted from the terminal device into a first group and a second group, the first-group access requirements being directed to the first recording medium, the second-group access requirements being directed to the second recording medium, and a section for executing the first-group access requirements and then executing the second-group access requirements. <IMAGE>
