PURPOSE:To prevent the contact of a terminal part and an angle part when a drawing circuit substrate is bent and drawn by providing a relay substrate and the drawing circuit substrate and covering the angle part of a head base by the extruding part of the base film of the relay substrate. CONSTITUTION:The relay substrate 52 and the drawing circuit substrate 62 are formed by laminating the base films 46, 56, copper foils 48, 58 and protecting films 50, 60. A magnetic head 12 is fixed to a metal base 14 to record and reproduce a magnetic tape. The base 14 has the extruding part 64 extruding from the angle part 15. The film 46 of the substrate is bonded to the base 14 and the copper foil 48 is soldered and fixed to the winding 13 of the head 12. The film 50 is soldered to the copper foil 58 of the substrate 62 by a solder 35. When the substrate 62 is bent in the direction of A and drawn, the extruding part 65 covers the angle part to maintain an insulation since the copper foil 58 does not directly contact the angle part. |
