Abstract

A tape driving apparatus and a recording medium, capable of detecting a target running amount during High Speed Search. Wherein upon a search command, a system controller sets a target position based on a specified position specified by this search command. Then, the system controller calculates the target running amount from the current position to the target position based on a spanned distance and calculates the target count value as the running amount corresponding to the calculated distance. Then, the system controller runs the magnetic tape while counting the reel FG pulses and shifts to High Speed Search. Starting High Speed Search, the system controller judges whether or not the count value of the reel FG pulses has reached the target count value. When it judges that the count value has not reached the target count value, it considers that the target position has not been reached yet and continues High Speed Search. When, it judges that the count value has reached the target count value, it shifts to Normal Search. After shifting to Normal Search, it judges whether the specified position has been reached or not based on information read out of the magnetic tape and when it judges that the specified position has not being reached yet, it continues Normal Search. When it judges that the specified position has been reached, it ends the search.
