Reducing air flow exposure to conductive components of a hard disk drive

A method for reducing air flow exposure to conductive components of a hard disk drive, said method comprising:

• providing a smooth passageway of airflow over an arm of an actuator, said airflow originating from a rotation of at least one disk and flowing over a surface of said at least one disk, said smooth passageway provided over a boss, said boss coupled with a first surface of said actuator, wherein said actuator is mounted to a housing and is movable relative to said at least one disk, said actuator having a suspension for reaching over said at least one disk, said suspension having a head gimbal assembly thereon,
• wherein said actuator comprises said first surface and a second surface opposite said first surface, and is coupled with a conductive component support that extends said first surface, said conductive component support comprises a support wall that attaches said conductive component support to said actuator, said support wall extending above said first surface, said conductive component support configured for supporting at least one conductive component thereon, said conductive component support having a conductive component entrance portion positioned between a flat coil of said actuator and said head gimbal assembly, and
• wherein said boss comprises a first end facing a flat coil side of said actuator and a second end facing a head gimbal assembly side of said actuator, wherein said first end extends further toward said flat coil side than said conductive component entrance portion such that a portion of said boss overlaps a portion of said conductive component support.
