Estimating the term…
A hard disk drive (HDD) using magnetic recording includes one or more components that directly contact the recording media. Such direct contact HDD components can be formed from an alloy including iron and at least one non-iron metal, such as nickel, cobalt or chromium. The recording media can be formed from a material having a low coefficient of thermal expansion (CTE), such as borosilicate glass. Forming the HDD components from the iron alloy, which also has a low CTE, makes the HDD components well suited for use with the low CTE recording media because the difference in CTE values is within an acceptable range, thus avoiding or minimizing any distortion to the media. The HDD components can include a disk spacer, a motor hub or a disk clamp.
A hard disk drive comprising:
A component configured to be positioned in a hard disk drive to directly contact a recording disk, the component formed of at least one of a first ternary alloy of iron-nickel-cobalt and a second ternary alloy of cobalt-iron-chromium, wherein the component is chosen from a motor hub, a spacer, a disk clamp, and combinations thereof.
A method of assembling a hard disk drive, the method comprising:
