Airflow shroud for HDD tracking microactuator
View Patent ↗An airflow shroud for either a moving-slider-type or a moving-head-type microactuator of a disk drive reduces off-track motion of a read/write element for either a moving-slider-type microactuator or a moving-head-type microactuator. One configuration of the airflow shroud includes a frame portion and an attachment portion. The frame portion has an opening suitable for exposing an air bearing surface of a slider for a disk drive and surrounds the slider and a moving-slider-type microactuator coupled to the slider. The attachment portion is adapted for attachment to a suspension of a disk drive. Another configuration includes a plate portion and a recessed portion. The plate portion is attachable to a slider having a moving-head-type microactuator. The recessed portion corresponds to the moving-head-type microactuator of the slider.
1. A disk drive including an airflow shroud for a moving-slider-type microactuator, comprising:
a first end of a flexure directly coupled with a suspension load beam;
a second end of said flexure directly coupled with a slider-type microactuator;
a slider directly coupled with said slider-type microactuator; and
an airflow shroud coupled with said flexure and with said suspension load beam such that said flexure is disposed between said airflow shroud and said suspension load beam, said shroud comprising:
a frame portion forming an opening for exposing a protruding portion of said slider, the frame portion surrounding said moving-slider-type microactuator coupled to the slider, said frame portion not contacting said suspension load beam said frame portion including a portion substantially covering a leading end of said slider; and
an attachment portion adapted for attachment with said suspension load beam wherein said frame portion is configured to not surround said suspension load beam.
2. The disk drive according to claim 1 , wherein the frame portion has side portions forming the opening and a tapered shape between each side portion and the opening.
3. The disk drive according to claim 1 , wherein between about 50 to 100 micrometers of the slider protrude through the opening of the frame portion.
