Abstract
A data storage device may have at least a slider constructed with at least one feature positioned on an air bearing region and separated from a data transducer. The at least one feature can be configured to provide a slider stiffness that decreases modulation while the at least one feature is floating above or in contact with a data storage media.
Claims20
An apparatus comprising:
- a slider having at least one feature positioned in an air bearing region and separated from a data transducer positioned on a transducer protrusion, the at least one feature comprising an increasing elevation having a continuously curvilinear cross-section shape within a perimeter defined by an air bearing wall, the data transducer separated from the air bearing wall, the at least one feature configured to provide a slider stiffness that decreases modulation and allows data access operations to be conducted while the at least one feature and transducer protrusion are each floating above and while the at least one feature and transducer protrusion are each in contact with a data storage medium.
A method comprising:
- providing a slider having at least one feature on an air bearing region, the at least one feature comprising an increasing elevation having a continuously curvilinear cross-section shape within a perimeter defined by an air bearing wall, the air bearing wall separated from a data transducer positioned on a transducer protrusion;
- and
- configuring the at least one feature to produce a slider stiffness that decreases modulation and allows data access operations to be conducted while the at least one feature and transducer protrusion are each floating above and while the at least one feature and transducer protrusion are each in contact with a data storage medium.
A method comprising:
- providing a slider having at least one feature positioned on an air bearing feature and comprising an increasing elevation having a continuously curvilinear cross-section shape within a perimeter defined by an air bearing wall, the air bearing wall separated from a data transducer positioned on a transducer protrusion;
- configuring the at least one feature with a varying side profile to provide a predetermined slider stiffness that decreases modulation while the at least one feature and transducer protrusion are each floating above that data storage medium and while the at least one feature and transducer protrusion are each in contact with data storage medium;
- and
- recording data to a data storage medium while the at least one feature successively floats on an air bearing and maintains contact with the data storage medium.
