構成としている。(Purpose of the invention) In view of the above points, the present invention has a structure in which a groove for adjusting the tail is provided on the side of the head pedestal to which the head body is fixed, and a screw for adjusting the tail is provided on the side of the fixed pedestal. A magnetic head that makes it possible to accurately adjust the height of the tail adjustment screw on the fixed pedestal side, improving accuracy, and making installation work easier by eliminating the need for height adjustment after the head is installed. This is what we are trying to provide. The present invention is a magnetic head in which the head body is fixed on a head pedestal and the head pedestal is placed on the fixed pedestal, and one protrusion is provided on the fixed pedestal side, and one tilt adjustment screw with a pointed tip is provided. The screws are screwed together, and the head base is provided with a positioning hole that engages with the protrusion and a long groove with a V-shaped cross section for tilt adjustment that abuts the tip of the tail adjustment screw.

る。 In FIG. 3, a recording/reproducing head body 1 for a VTR is fixed to a head pedestal 2A with screws or the like, and a through hole 5A for positioning is formed in the head pedestal 2A, and a tilt adjustment is made on the surface facing the fixed pedestal 6A. A long groove 7A having a V-shaped cross section is formed. on the other hand,
A screw hole is formed in the fixed pedestal 6A, and the tip of the screw hole has the V-shaped long groove 7A in cross section for tilt adjustment.
Tail adjustment screw 4A with a pointed tip that hits the
are screwed together, and a cylindrical projection 8A that fits into the through hole 5A is formed. A pair of mounting azimuth screw holes 10 are formed in the head pedestal 2 for screwing from the fixed pedestal side. The head pedestal 2A with the head main body 1 integrated has a cylindrical protrusion 8A fitted into the positioning hole 5A, and the tail adjustment screw 4A has a V-shaped long groove 7A in abutment against the tip of the tail adjustment screw 4A. It is fixed to the fixed pedestal 6A and mounted on the device.
