Claims

[Scope of utility model registration request]

(1) In a magnetic head for a video tape recorder, which includes a shield block, an audio head control head, and a resin-filled case, the magnetic head has a surface that comes into contact with the shield block, and a surface that is parallel to the magnetic head. The block holder has two surfaces perpendicular to these surfaces and parallel to each other, and further includes a block holder having a bottomed hole in the surface parallel to the contact surface of the shielding jig. A magnetic head for video tape recorders.

(2) The magnetic head for a video tape recorder according to claim 1, wherein the bottomed hole has a circular cross-sectional shape and has a partially tapered portion.
