In the inspection, the head is attached to the head arm to form a head assembly, which is clamped on a mounting table and moved by a carriage mechanism to seek the head with respect to the magnetic disk. The conventional head assembly 1 shown in FIG. 2 (a) has a head arm 1b.
A head 1a fixed to one end thereof and a base portion 1c having an elliptical hole 1d for positioning formed at the other end thereof. FIG. (B) shows a conventional clamp mechanism 2, which includes a mounting table 21 having a positioning protrusion 211 and a slide rod 212,
It is composed of a fixed portion 22 through which the slide rod penetrates, and two pressing pieces 23 for pressing both side surfaces of the base portion 1c. The head assembly 1 is mounted on the mounting table 21 by inserting the projection 211 into the elliptical hole 1d, and when the slide rod 212 is moved in the direction of arrow A by a drive mechanism (not shown), the mounting table moves and the projection 211 becomes an elliptical hole. The base portion is pulled rightward by contacting the edge P of 1d, and the reference line K abuts on the fixed portion 22 to perform positioning in the front-rear direction and angle determination in the lateral direction. Then, two pressing pieces 23 press both side surfaces of the base portion 1c to clamp them on the mounting table.

を目的とするものである。Recently, due to the progress of magnetic media, the recording density has increased and the size of magnetic disks has decreased, and in response to this, ultra-small thin film heads have emerged. Corresponding to this, the head assembly is also much smaller than before. FIG. 3 shows a miniaturized head assembly 3 in which the head arm 3b is made of a lightweight thin plate by bending both sides to increase strength, and a square spacer 3c for welding is welded to the base for positioning. .. A circular hole 3d is formed in the center of the spacer 3c.
Is perforated and the edge of its circumference is
A chamfered slope having an angle θ is formed with high accuracy. In this case, a point (or circumference) Q at the lower end of the slope at the front edge of the circular hole is used as a reference point for positioning in the front-back direction. Further, the trailing edge of the spacer 3c is also finished with high precision and is used as a reference line K for determining an angle with respect to the lateral direction. In this way, the head assembly 3 is different from the conventional head assembly 1 shown in FIG. 2 (a) in how the reference for positioning and angle determination is taken, and therefore the conventional clamp mechanism 2 is not suitable for the head assembly 3.
A new clamp mechanism is needed. The present invention has been made in view of the above, and an object of the present invention is to provide a mechanism for clamping a head assembly, which is miniaturized corresponding to an ultra-compact thin film head, with stable and reliable positioning and angle determination. It is a thing.
