Abstract
A compliant, flexible air bearing slider (ABS) reduces the contact forces between the slider and disk, thereby reducing excessive burnishing and wear and increasing the reliability of the slider. According to an embodiment, an ABS has at least one “compliance-enhancing feature” which reduces the bending mode vibration frequency of the slider. By causing the slider to flex, and bringing the bending mode vibration frequency closer to the pitch 2 eigenmode frequency, coupling of the different vibration modes can be obtained. Thus, the different vibration modes can effectively dampen each other and result in reduced contact forces between the slider and disk.
Claims25
An air bearing slider, comprising:
- a compliance-enhancing feature which affects slider bending mode frequency and slider pitch mode frequency, wherein said compliance-enhancing comprises one or more recesses in said slider.
A hard disk drive device comprising:
- a base;
- a magnetic storage medium assembly coupled with said base, said magnetic storage medium rotatable relative to said base;
- and
- one or more actuator arms housing a corresponding slider housing a corresponding read/write head for reading data from and writing data to said magnetic storage medium, said slider comprising a compliance-enhancing feature which affects slider bending mode frequency and slider pitch mode frequency, wherein said compliance-enhancing comprises one or more recesses in said slider.
