Recording medium library system

摘要

A recording medium library system retaining up to a predetermined number of cartridge type recording media for recording/reproducing data on the recording medium is disclosed. The recording media are stored in a plurality of cells provided in a cell drum. The cell drum is rotatably driven such that a desired cell is brought to a target position. In the driving, an accelerating current, a braking current, and a positioning current are supplied to the motor in order of mention. At least the braking current is determined according to an input value of the inertia of the cell drum.
