K. 0 Regarding Manufacturing Method of Magnetic Head Assembly for Fixed Head Type Magnetic Disk Device Conventionally, a fixed layer magnetic head has a spring property, and the gimbal, load arm, and spacer are assembled at the required dimensional positions by spot welding. Furthermore, the *SV-treated core slider was held with a gimbal to form a companion assembly, and multiple pieces were attached to this assembly T-frame and R was assembled. This jingle assembly is arranged and attached radially at equal intervals in the radial direction from the center of the frame.
The LJC frame had a structure in which a printed circuit board T-configured with read and write circuit tubes was fixedly attached, and was connected by soldering to the circuit terminal of the printed board on the end of the winding from the core slider. In the so-called fix-boost assembly,
The read and write gaps of the core slider attached to the gimbal must be positioned with high precision in the radial direction of the frame in line with the tracks of the magnetic disk. 1
- It is necessary to do it with high precision. If the core slider is installed in the wrong position, it will be inconvenient to read the adjacent track information of the magnetic disk as noise.
Furthermore, there is the inconvenience of thermal off-track generation leading to leads and 100-second occurrences.In addition, there are many assembled parts,
In addition, since the processing procedure is complicated in multiple stages, there is a drawback that high-precision positioning requires careful consideration and a skilled team.The purpose of the present invention was made in view of the above problems, and it is The manufacturing method of the magnetic head assembly according to the present invention to achieve the present invention is to simplify the assembly and thereby improve the processing accuracy after assembly. Then, a plurality of tongue shapes are fully formed and arranged by notching the magnetic disk at the locations corresponding to the track positions, and then the tongue shapes are folded and processed to form the support part of the magnetic head. It is characterized by being attached and fixed to the gimbal part of the core slider IP# support part, which is marked with lines, and will be explained in detail below according to the drawings. FIG. 2 is a plan layout diagram of a magnetic head support section. In the figure, lFi springy thin veneer,
2 is a support part, and the support S! are arranged in a concentric spiral pattern according to the track position of the magnetic disk 4 (see Figure 311). Figure 2 is a diagram of the processed shape of the support part in Figure 3911. -7

ある。This O11 overlap position is a position where the center of the read/write gap coincides with the center of track 9. The core slider 13 has three read/write gaps 8,
Each read/write gap $ independently tracks 9
The 11t support has one support part! (II intention) Three magnetic heads! IO is provided. Therefore, if there is one track on the surface of the magnetic disk 10, the magnetic head sO
Since one support part 2 (Fig. 92) is required, it is better to install it on the φ side.The installation position of the thin veneer 1#i magnetic head 50 is spot welded or Fix with adhesive and further solder the tip of the 0-core slider 130 winding II (not shown) and the circuit terminal (not shown) attached *a to the back of the printed board 12Yr frame 11 on which the circuit is mounted.◎ Book -According to the embodiment, the processing of the tongue shape that becomes the support part is easy, and the positioning accuracy is improved.The arrangement position of the tongue shape according to the present invention is limited to the present embodiment. For example, instead of a spiral arrangement, a wave arrangement is also possible, and any arrangement that can cover all the radial positions on the magnetic disk is sufficient.Furthermore, the shape of the support part is not limited to this example. Any shape or structure can be used as long as the load arm has rigidity and the core slider of the gimbal can be held with a predetermined springiness.Thus, according to the present invention, the number of parts can be reduced and the processing procedure can be improved. Simplification has the effect of easily improving assembly accuracy.
