整機構。 A mechanism for adjusting the position of the magnetic head of a magnetic recording and reproducing device that has a rotating head cylinder and a fixed magnetic head and records and reproduces video, audio signals, or control signals using a magnetic tape as a recording medium. A spindle installed in the base member and a magnetic head are placed thereon, and the magnetic head is rotatable in the magnetic tape running direction about the spindle as a central axis, and also movable in the axial direction of the spindle. a magnetic head adjustment plate pivotally supported on the support shaft; an elastic member for biasing the magnetic head adjustment plate in the axial direction of the support shaft and in a direction to rotate the magnetic head adjustment plate; and a rotation of the magnetic head adjustment plate. a taper that comes into contact with one end remote from the moving shaft to lock its rotation, and is movably held by the base member or a member fixed thereto by a threaded structure substantially parallel to the axial direction of the support shaft; and a stopper member that is movable in the axial direction on the support shaft and that contacts the magnetic head adjustment plate near the rotation axis to lock the axial movement of the magnetic head adjustment plate. A magnetic head adjustment characterized in that the tapered surface portion of the magnetic head adjustment plate or the contact portion of the magnetic head adjustment plate that contacts the adjustment member is made smooth by any method such as applying lubricant or polishing to reduce the coefficient of friction. mechanism.
