摘要：
A tape drive controlling device includes a first controlling circuit for driving a take-up reel for a tape on the basis of the result of a comparison between a take-up-side tension measured between the take-up reel and a head and a predetermined tension target value, a second controlling circuit for driving a supply reel for the tape on the basis of the result of a comparison between a supply-side tension measured between the supply reel and the head and a predetermined tension target value, a speed detecting circuit for detecting the travel speed of the tape, and a correcting circuit for correcting at least one of the take-up-side and supply-side tension target values on the basis of the result of a comparison between a detection result provided by the speed detecting circuit and a travel speed target value.
