ABSTRACT:
A method for controlling tape running in a tape driving apparatus in which the size of a hub is determined when a tape is inserted into the tape driving apparatus and the number of reference pulses corresponding to one rotation of the reel in an end position of the tape is calculated according to the determined size of the hub. The tape is run and the frequency of rotation of the reel is detected. A comparison is made between the number of pulses of the present reel and the number of reference pulses, and if the number of pulses of the present reel is smaller than the number of reference pulses, the running mode is continuously performed. If, however, the number of pulses of the present reel is larger than the number of reference pulses, then a stop position is judged and the tape running is stopped, resulting in entering into a stand-by mode.
