Abstract

PURPOSE:To restore an error in the desired range of storing data at the time of generating the failure of a storing medium by forming R mutually different redundant data groups from K division data groups to have the data groups of K+R=N and adding a self-inspection function code to the N piece's data. CONSTITUTION:According to a processing previously selected from many redun dant processings, the R mutually different redundant data groups are formed from the K division data groups, added to original data group to have the data groups of K+R=N and the N data self inspecting function codes are added and written in the N mutually independent storing areas of a storage device. According to the self-inspecting function code, the error of read data is inspected, the R redundant data is sequentially read according to the number of the detections of the errors, the data recognized to have no error according to the self-inspecting is added to set the data of K in the sum. Thereby, at the time of generating the failure in an external storage device, the error within the desired range of the storing data can be recovered.
