Abstract

PURPOSE: To avoid the tape end signal from being ineffective to the rewinding reel, by automatically stopping the tape running and informing to the upper rank unit, through the provision of the counter counting the forward position of tape after passing through the tape end signal.
CONSTITUTION: When the tape end signal EOT is detected after the start of magnetic tape running, the detection hold circuit 2 is operated and the counter enable input CE of the counter 5 and the ROM readout enable signal A are made to 1, and the output of the ROM 4 is set to the counter 5, to start count down. When the write-in/readout/read-skip in data block unit is finished, the tape run stop signal is at 1, FF11 and 16 are reset, the generation of the clock of the circuit 12 is stopped, and the counter 5 is temporarily stopped. Further, the tape run is stopped and the functional block informing the stop of tape run to the software is started.
