INFORMATION RECORDING METHOD AND INFORMATION RECORDING/REPRODUCTION DEVICE

摘要

If is possible to eliminate failure of correct recording on a recording medium in an on-vehicle audio recording/reproduction device due to an instantaneous power cut-off or the like. In order to achieve this object, a file system is used for managing files hierarchically by using files having information and a directory as a storage place of the files so that predetermined information is recorded in a work sector for back up before performing the primary recording. The work sector is selected from a work sector region having a plurality of sectors and the work sector has recorded the number of mountings of the file system. Thus, an optimal work sector is used for data recovery.
