Abstract

PURPOSE: To efficiently manage data by combining a recording medium which is exclusively used for readout and a recording medium which can be used for writing and readout any time.
CONSTITUTION: In case the data of a data storing means 7 which is exclusively used for readout is to be supplemented or modified, only the adding or modifying data are written in a data storing means 6 which can be used for writing and readout any time and the index information of an index information storing means 5 is modified by means of an index information processing means 4. When the data are retrieved again, the data of the data storing means 7 and 6 are outputted. Therefore, the readout-only data storing means, such as a CD-ROM, etc., can be used as if the data stored in the data storing means can be supplemented and modified.
