Abstract
PURPOSE: To prevent the malfunction of tape unit due to the dispersion in the characteristics, by produding the recording end signal and stopping the running of magnetic tape when the write-in time is elapsed.
CONSTITUTION: The designation signal given via the instruction designation signal line 11 from the logic unit 1 is interpreted at the instruction decode circuit 2, and it is given to the write-in format control circuit 3 or tape mark format control circuit 4 via the write-in instruction signal line 12 or tape mark instruction signal line 13. Further, in the circuit 3 receiving the data via the data line 21 from the unit 1, the format of data is converted to the magnetic tape unit 8, or it is transferred via the write-in data line 18 as it is. Further, after the end of write-in, based on the read-in data given via the read-in data 14, the inter block gap IBG is formed 5, and when the supply of the read-in data is finished, IBG forming end is informed to the running stop circuit 7 via the IBG forming end signal line 16.
