<p>PURPOSE: To provide a magnetic device which can guide a tape without abrasion even with maximum tape width by bringing a pair of inner tape guide elements on both sides of a magnetic head into contact with one edge of the magnetic tape and bringing a pair of outer tape guide elements into contact with the other end of the magnetic tape. CONSTITUTION: The mutual distances of guide rims 9a, 9b, 9c and 9d in a pair of tape guide elements 9 are made into sizes corresponding to the maximum tape width Bmax of the magnetic tape The positions of the guide rims 9b1 , 9b2 , 9c1 and 9c2 of the tape guide elements 9 against the tape edge of the magnetic head 7 and against the tape guide elements 9a and 9d on outer side are adjusted so that one edge 11d of the magnetic tape 11 is brought into contact with the guide rims 9b1 and 9c1 of the magnetic head 7 and the other edge 11c is brought into contact with rims 9a2 and 9d2 of the other pair of the tape guide elements on the outer side. The tape guide elements 9 and a head positioning holder are integrally injection molded.</p> |
