Abstract
An air bearing surface of a slider, which achieves low crown sensitivity is described. In one embodiment, the air bearing surface comprises a center channel and a plurality of side channels, wherein at least one side channel of the plurality of side channels is open to the center channel. The center channel and the plurality of side channels are configured to allow air to flow along the center channel toward the trailing edge of the ABS, such that there is low crown sensitivity.
Claims20
An air bearing surface (ABS) of a slider, wherein said ABS achieves low crown sensitivity, said ABS comprising:
- a center channel;
- and
- a plurality of side channels, wherein a first channel of said plurality of side channels is located proximate to an outer diameter (OD) of said center channel and is sealed off from said center channel, and wherein a second channel of said plurality of side channels is located proximate to an inner diameter (ID) of said center channel and provides the only opening into the center channel from a side of the slider, and wherein said plurality of side channels is configured to allow air to flow along said ABS toward the trailing edge (TE) of said ABS, such that there is low crown sensitivity.
A data recording device comprising:
- a disk with a data surface of concentric data tracks;
- a rotator for rotating said disk about an axis generally perpendicular to said disk;
- a slider maintained in operative relationship with said data surface when said disk is rotating, said slider having an air bearing surface (ABS), wherein said ABS achieves low crown sensitivity, said ABS comprising:
- a center channel;
- and
- a plurality of side channels, wherein a first channel of said plurality of side channels is located proximate to an outer diameter (OD) of said center channel and is sealed off from said center channel, and wherein a second channel of said plurality of side channels is located proximate to an inner diameter (ID) of said center channel and provides the only opening into the center channel from a side of the slider, and wherein said plurality of side channels is configured to allow air to flow along said ABS toward a trailing edge (TE) of said ABS, such that there is low crown sensitivity;
- a transducer attached to said slider for reading data from and writing data to said data surface;
- an actuator for moving said slider generally radially to said disk to allow said transducer to access said concentric data tracks;
- and
- an electronics module for processing data read from and written to said data surface.
An air bearing surface (ABS) of a slider, wherein said ABS achieves low crown sensitivity, said ABS comprising:
- means for defining a center channel;
- means for defining a plurality of side channels, wherein a first channel of said plurality of side channels is located proximate to an outer diameter (OD) of said center channel and is sealed off from said center channel, and wherein a second channel of said plurality of side channels is located proximate to an inner diameter (ID) of said center channel and provides the only opening into the center channel from a side of the slider, and wherein said plurality of side channels are configured to allow air to flow along said ABS toward a trailing edge (TE) of said ABS, such that there is low crown sensitivity.
