Data recorded on magnetic tape is read by a read head after a specific constant period of time determined by the interval between the write head and the read head and the transfer speed of the magnetic tape. The writing checking system determines whether or not the data written on the magnetic tape by the write head may be read by the read head after a specific predetermined period of time. There is a period of time between the writing of the data on the magnetic tape by the write head and the passage of the data under the read head. Such period of time is utilized to predetermine the time at which the data should not be read by the read head and the time at which the data should be read by the read head and to check whether or not the data read by the read head satisfies the predetermined condition, thereby enhancing the reliability of the writing.
