Abstract
A tape drive comprising a processor which determines a position to which to move a recording tape without detecting inter-segment gaps on the tape. The tape drive includes a drive motor which periodically outputs pulses during rotation. The rotation of the motor and the displacement of the tape are linearly related. When the processor receives an instruction to move the tape a predetermined number of segments, the number of segments is converted into a length based on the format of the tape. The length is correlated to a total number of motor pulses to be counted as the tape is moved in order to stop the tape at proper location.
