Abstract

PURPOSE:To eliminate the effect on the postprocessing, even if a magnetic tape is taken out before the end of data recording of all blocks, by recording a mark one block after further at every data recording of one block. CONSTITUTION:A cassette magnetic recorder 3 is controlled via CPU5 in accordance with a program in an ROM6 and data of one block is recorded, then the cassette tape is forwarded further by one block and an end mark is recorded. At the recording of the next block, the data for one block's share is reversed and after the mark is erased, the recording of data is made with a similar system as the said block and the end mark is always recorded. Thus, even at the rerecording after unloading of a magnetic tape before the end of recording is not made due to failure in the cassette or the like, since the preceding recording is surely discriminated, the confusion of collected data and the like can be avoided.
