<P>PROBLEM TO BE SOLVED: To provide a method for managing a file of a semiconductor device, which prevents file corruption even when power supply is interrupted during file write while securing an available data area, and to provide an information recorder. <P>SOLUTION: The information recorder 4 has the semiconductor device 3 and a file management device 2. The semiconductor device 3 is provided with: a data area 13 having a plurality of blocks, system areas 11 and 12 for storing management information of the data area, and a write information holding area 14 for temporarily storing update management information for updating management information of the system areas. The file management device 2 writes an update file in a free block of the data areas, writes the update management information with the update file written thereto in the write information holding area, updates the management information of the system areas on the basis of the update management information written in the write information holding area, and deletes the update management information in the write information holding area. <P>COPYRIGHT: (C)2010,JPO&INPIT |
