High-speed audio/video information server and magnetic disk device extension method thereof

摘要

An HDD array is extended in a high-speed AV information server and then a restructuring instruction (41) is generated and restructuring operation (42) is executed If a reproduction request (43) is issued to storage information which is being restructured information processing (44) for interrupting the restructuring operation is carried out and a display (29) of a region which is being restructured is passed so as to reproduce the storage information. At the end of reproduction (47) after executing the reproduction operation (46), the reproduction operation (48) is resumed to thereby allow the access even while storage information is being restructured.
