Abstract: A multi-slope load/unload ramp for a hard disk drive includes an inner first portion having a non-horizontal first slope and an adjacent outer second portion having a different non-horizontal second slope. The first slope may be steeper than the second slope, and the ramp may further include a third portion adjacent to the second portion and also having a third slope steeper than the second slope, with the ramp configured for positioning the first and second portions to overlap the disk while the third segment may be in part outside the disk. The second slope may be steeper than the first slope, with the ramp configured for positioning the first portion to overlap the disk while the second portion may be in part outside of the disk. Hence, any slider rebound from the steeper portions would occur outside of the disk and avoid a slider-disk crash.

Abstract: Disclosed herein are sliders with at least one notch-cut 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 at least one notch-cut (e.g., two notch-cuts) in a trailing side of the trailing pad. The at least one notch-cut provides higher pressure at the recording head situated in the trailing pad and higher thermal flight control efficiency without a commensurate increase in touch-down power. As a result, the temperature around the recording head is lower than without the at least one notch-cut, thereby improving the lifetime of the recording head and data storage device.

The ramp also comprises an inclined surface along which the lift tab slides as it moves in a first direction to remove a read/write head from a disk of the hard disk drive. The inclined surface inclines from a leading edge of the ramp to an intermediate edge of the ramp in the first direction. The inclined surface has a width that is generally perpendicular to the first direction and extends from the first side to the second side. The inclined surface has a width that is generally perpendicular to the first direction and extends from the first side to the second side. The tapered portion defines an oblique angle relative to the first direction.
