Abstract

PURPOSE:To improve the utilizing efficiency of an optical disk by recording record change information to a store control information area to express the change condition of a correspondent relation between the logical order and the physical order of record. CONSTITUTION:A logical record number is a logical order number to be set to the physical record of the record to constitute the data file and a physical record number is an order number to express the recording position of the record in an area secured in the data file. The record to constitute the data file is successively added and recorded to a data area and the record change information are recorded to the storage control information area to express the change condition of the correspondent relation between the logical order and the physical order of the record. Then, the data file is re-constituted by using the record change information. Thus, a storing area, which is used at a record changing time, can be suppressed and the utilizing efficiency of the optical disk can be improved.
