摘　　要：介绍一种记录系统信息表的设计方法,并根据实践经验提出优化措施。通过对信息表进行备份、对备份信息表单独刷新、对备份信息表位置的精心设计等措施,保证信息表能效记录数据关键信息,并且两份信息表不会同时被破坏。通过对备份信息表的自动读取保证系统在一个信息表遭到意外破坏时系统仍能正常工作,并自动恢复被损坏的信息表,在数据保护和系统稳定工作方面具有重要意义。This paper introduces a method of designing information table in recording system and gives an optimized method used in actual applications. The designing method ensures that information table can recording important information of the recorded data and two information tables will not be destroyed at the same time through backupping the information table,separately updating backup information table and carefully placing backup information table. The recording system ensures that when one of the two information table is destroyed, the recording system can work normally and recover the destroyed information table through getting the other automatically. It is significant to data - protecting and the recording system reliably working.
