Abstract

PURPOSE:To enable positioning of recording and playback heads at a specified spacing on the same track of a magnetic tape by unitizing a head holding plate and tape guide to one body and displacing a head base which holds both heads in two directions; the plane direction of the head holding plate and the direction perpendicular thereto. CONSTITUTION:The magnetic tape 10 is guided and traveled by a tape guide 11 and a movable body 13 is moved in the transverse direction of the tape 10 by which the recording of data by the recording head 18 and the reproduction of the data by the playback head 19 are executed at every one track. The check items after assembly include the check of the positions of the head 18 and the head 19; first the spacing between the heads 18 and 19 is set slightly widely and the head base 20 is permanently deformed in the plane direction while the top end of a groove 22 is narrowed by a projecting part 25 which is pressed from the outside by a jig. The spacing between the heads 18 and 19 is thus adjusted. Adjusting screws 26 are then tightened to deform the head base 20 in the perpendicular direction on one side each, by which both heads 18, 19 are positioned on the same track of the tape 10.
