A new trailing pad structure with partially-etched pad is proposed. The effect of the pad shape, trench depth and width was numerically investigated and presented. The thermal protrusion efficiency of the new ABS design which has adopted the new trailing pad structure is also presented.
This paper presents a simulation study on the dynamic behavior of a femto slider in contact with the disk. A simulator is developed to calculate the interactions between the air bearing dynamics and vibrations of the slider-suspension assembly. The dynamic response of read/write head in both flying-height (FH) and off-track directions due to the slider-disk contacts can be obtained with this simulator...
This paper discusses the approach to design air bearing surface (ABS), which can achieve high air bearing (AB) stiffness and high air pressure (AP). Generally, in order to reduce flying height variation and improve the slider's flying stability, high AB stiffness and high AP are preferred.AB stiffness and AP is very sensitive to the slider's ABS design. The flying height and flying attitude of slider...
