Abstract
Disclosed herein are sliders with at least one notch in the trailing pad, methods of making them, and data storage devices comprising them. In some embodiments, a slider comprises a leading-edge surface, a trailing-edge surface, and an air-bearing surface (ABS) that includes a trailing pad situated closer to the trailing-edge surface than to the leading-edge surface, wherein the trailing pad comprises a main portion, a mini-pad situated between the main portion and the trailing-edge surface, and a neck portion connecting the mini-pad to the main portion, wherein a minimum width of the neck portion in a cross-track direction is less than a minimum width of the mini-pad in the cross-track direction.
Claims20
A slider for a data storage device, the slider comprising:
- a leading-edge surface;
- a trailing-edge surface, wherein the trailing-edge surface is substantially parallel to the leading-edge surface;
- and
- a trailing pad situated closer to the trailing-edge surface than to the leading-edge surface, wherein the trailing pad comprises:
- a main portion,
- a mini-pad situated between the main portion and the trailing-edge surface, and
- a neck portion connecting the mini-pad to the main portion, wherein a minimum width of the neck portion in a cross-track direction is less than a minimum width of the mini-pad in the cross-track direction.
A data storage device, comprising:
- a recording medium;
- and
- a slider comprising:
- a leading-edge surface,
- a trailing-edge surface substantially parallel to the leading-edge surface, and
- an air-bearing surface (ABS), comprising:
- a trailing pad situated closer to the trailing-edge surface than to the leading-edge surface, wherein the trailing pad comprises:
- a main portion,
- a mini-pad extending from the main portion toward the trailing-edge surface, and
- at least one notch between the mini-pad and the main portion of the trailing pad.
A data storage device, comprising:
- a recording medium;
- and
- a slider, comprising:
- means for writing to the recording medium;
- and
- a trailing pad, comprising:
- a main portion,
- a mini-pad extending from the main portion toward a trailing-edge of the slider, and
- a neck portion connecting the mini-pad to the main portion, wherein a minimum width of the neck portion in a cross-track direction is less than a minimum width of the mini-pad in the cross-track direction.
