Zusammenfassung:The magnetic disk device is used as a subsystem of a computer system, partic. of a medium-size computer system which uses the commercial power source, but not provided with its own backup power source. The device has a number of directors (118), a number of magnetic disk modules (148) accessible in common by multiple directions, several batteries (114-m) for supplying power individually to the directors. There are batteries (114-n) for supplying power to the magnetic disk modules and a power controller (110) which controls individually the power supplies from the batteries for the directors and the batteries for the magnetic disk modules in accordance with the operational conditions of the directors and modules.
