ABSTRACT:
A data reproducing device for reproducing a positional information track formed in the longitudinal direction of a magnetic tape according to the present invention is capable of easily correcting regenerative positional information on the basis of count information even when the regenerative information is not obtained from the positional information tack by obtaining the count information consisting of the number so updating operations of positional information in accordance with a first clock generated based on the regenerative positional information acquired from the positional information track formed in the longitudinal direction of the magnetic tape and with a second clock generated based on rotation frequencies of tape reels for driving the magnetic tape.
