摘要: In prior art memory systems, if a defective area of the recording medium is accessed for reading, an alternative area for compensating the defective area is read out. According to this invention, information recorded in the alternative area is stored in advance in a separate high-speed memory device and it is read out when the alternative area is requested to be read out.

摘要: A distributed information retrieval system in which the central computer is connected to a plurality of terminal devices and the management information includes a set of retrieval keys kept on the central computer side where the primary retrieval is achieved. The secondary retrieval thereafter is executed on the terminal side to reduce the load imposed on the central computer and to improve the response time for forwarding an answer to the user of the retrieval system.
