Abstract

This article describes a technique for attaching an actuator metal band to a capstan fixed to a motor shaft in a disk drive. The feature of this technique is using pins of material that can be welded to the band. Fig. 1 shows a head actuator comprising a motor 1, a capstan or pulley 2 and a metal band 3 wound around the capstan 2. The movement of the band 3 is transmitted to a head/arm assembly (not shown). (Image Omitted) The band 3 is usually made of stainless steel, while the capstan 2 is made of aluminum alloy. Thus, it is difficult to weld the band 3 to the capstan 2. To solve this problem, pins 4, made of stainless steel or other material which can be welded to the band 3, are at first press-fitted into the capstan 2, as shown in Fig. 2A. After polishing the edge surfaces of the pins 4 (Fig.

The band 3 is usually made of stainless steel, while the capstan 2 is made of aluminum alloy. Thus, it is difficult to weld the band 3 to the capstan 2. To solve this problem, pins 4, made of stainless steel or other material which can be welded to the band 3, are at first press-fitted into the capstan 2, as shown in Fig. 2A. After polishing the edge surfaces of the pins 4 (Fig. 2B), the band 3 is welded to the edge surfaces of the pins 4 (Fig. 2C).
