Abstract
PURPOSE: To make possible track servo and achieve the improvement in track density by making the width of each track of a multitrack type magnetic head smaller than servo track width and superposing the reproduction servo signal of dach track.
CONSTITUTION: A tape 1 is fed by motors 19, 20 and the reproduction signals from head gaps 12, 13 are amplified 16 to waveforms A, B. These both signals are then superposed in a circuit 15 to obtain the waveform C. The signal having this peak value is inputted to a discrimination circuit 17 which then discriminates that a mark 7 is before or after the peak value of the servo signal waveform and detects the time lag thereof. The correction direction and quantity are then supplied to a circuit 18. The circuit 18 drives the motor 19 which in turn feeds the tape 1, thereby performing positioning of the recording track and head gaps.
