Claims

[Scope of utility model registration request]

In a magnetic recording/reproducing device equipped with a rotating head assembly having a fixed upper drum and a rotating middle drum, the thickness of the tape contacting surface of the rotating drum is the same as the thickness of the head chip, or
or approximately the same value, and the diameter of the rotating drum is the same as or slightly smaller than the rotational diameter of the tip of the head tip, and furthermore, the diameter of the rotating drum is the same as that of the head tip stand, and the diameter of the rotating drum is the same as that of the head tip stand, or the diameter of the head tip stand is made to be the same or slightly smaller. A magnetic recording/reproducing device characterized in that shaped dummy chip stands are mounted facing each other.
