INFORMATION RECORDING METHOD, AND INFORMATION RECORDING OR REPRODUCTION DEVICE, AND INFORMATION RECORDING/REPRODUCTION DEVICE

摘要

PROBLEM TO BE SOLVED: 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. SOLUTION: A file system is used for managing files hierarchically by using files having information and a directory as a storage place of a plurality of files so that predetermined information is recorded in a work sector for backup before performing the primary recording. The work sector is selected from a work sector area 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. COPYRIGHT: (C)2011,JPO&INPIT
