A cleaning tape structure is provided for removing dust from a magnetic head tip, The dust on the head tip is collected by the membranes installed on the tape surface. A laser beam is used to make vertical cuts on the tape surface in several oblique arrays of grooves. The dust is removed by the cutting edges formed by the peripheral edges of the grooves and then collected by the membranes installed at the end of each of four tape sections. The four sections also function to indicate the remaining life of the head tip, based on the number of sections which must pass the head tip before a picture prerecorded on the cleaning tape can be clearly viewed.
