  • Patent number: 10720179
    Abstract: Exemplary methods and apparatus are disclosed for a head assembly of a hard disk drive. In one example, a tilt-preventing standoff or datum is formed on a flexure cover layer of a head assembly of the hard disk drive to prevent tilting of a slider of the head assembly relative to the flexure cover layer during fabrication. The flexure cover layer may be, e.g., a laminate cover layer that covers and protects the flexure of the head assembly. In some examples, a primary standoff (or adhesive limitation) is formed on the flexure layer and shaped to limit the spread of an adhesive. The tilt-preventing standoff is a secondary standoff or datum that is sized and positioned to prevent tilting of the slider relative to the flexure cover layer during mounting of the slider to the flexure cover layer. The primary and secondary standoffs may be formed, for example, of polyamide.
