Abstract: A method of manufacturing hard disk drives (HDDs) includes assembling a first HDD including a first slider having a first air bearing surface (ABS) configuration, configuring the first HDD to rotate its disk media at a first revolutions-per-minute (RPM), and sealing the first HDD with a first internal pressure level. Continuing, the method includes assembling a second HDD including a second head slider having the same first ABS configuration, configuring the second HDD to rotate its disk media at a second RPM that is lower than the first RPM, and sealing the second HDD with a second internal pressure level that is higher than the first pressure level. Thus, in the context of using a common slider among different RPM drives, a higher internal pressure for the lower RPM drive can compensate for loss in fly height that might otherwise occur due to the lower operational RPM.

Therefore, a dynamic management of the domain controller system may be completed, and a high expansibility and high availability of performance of the domain controller system may be ensured.

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.
