Slits are strategically formed between the outrigger portions and the opposite side edges of the tongue portion. The design ensures that the tongue portion and the outrigger portions are effectively connected by connecting portions. Additionally, limiter members are formed on the load beam, each equipped with a bent portion that fits into corresponding slits. The trace member is electrically connected to the slider and extends along the outrigger portions.

The head suspension for a hard disk drive is designed to be thin from the arm to the head, minimizing the step between the arm and the load beam. This head suspension includes a load beam that consists of both a rigid part and a resilient part. The load beam applies necessary load onto the head, which is positioned at the front end to read and write data from the disk. The head is connected to read/write wiring patterns of a flexure, which supports the head and is attached to the disk-facing surface of the rigid part.
