Abstract

PURPOSE: To prevent the final record from making a decision error, by additionally recording a record having an identifier which shows the end, immediately after the final record.
CONSTITUTION: The index mark 30 showing an initial point of the track is made the initial point, and the records 31... having a regular identifier 37, respectively, are recorded. The recording is performed in the magnetic disk, etc. so that the end record 36 having an identifier 38 which shows the end can be further added immediately after the final record 35. By means of said system, it is possible to realize a recording system of high reliability, by which a decision error, overlooking, etc. of the final record 35 do not occur even in case such malfunctions as overlooking of the address mark, synchronizing shift, etc. have continued, nor occurs a decision error of the final record in case of reading or writing a record data of one track.
