ABSTRACT:
Embodiments of the present invention provide a highly reliable hard disk drive (HDD). In an HDD according to an embodiment of the present invention, solder at a solder joint for joining a pad of a head slider and a pad of a transmission wiring comprises the main component of Sn and atomic percent to atomic percent of indium. The solder exhibits the γ phase within the range of −150° C. to 120° C. Accordingly, even if the HDD is left at a low temperature for a long time, the solder joint is not broken.
