<P>PROBLEM TO BE SOLVED: To prevent disappearance of data in a storage having a data retention period in which the data can be retained even after power supply is stopped, even when an information processor is not turned on for a long period. <P>SOLUTION: An information processor 1 includes: a storage medium (NAND Flash) 33 capable of continuously retaining data in a data retention period even after power supply is stopped; and a control unit 32 for determining whether the data retention period elapses from a final confirmation date and time (a start date and time of the data retention period of the recording medium 33) stored in a CMOS RAM 36 and a current date and time indicated by an RTC 37 (S303), and, when determining that the data retention period elapses (S303: No), preventing the information processor 1 from starting up (abnormal termination). <P>COPYRIGHT: (C)2012,JPO&INPIT |
