摘要： To allow for adjusting the fly height of a read/write head carried by a slider, a shear transducer is added to the slider. The shear transducer comprises a layer of piezoelectric material added to the slider so that the portion of the slider carrying the read/write head can be moved when the shear transducer is sheared. To cause the shear transducer to shear, a voltage is applied across the piezoelectric layer. To control the movement of the transducer, a closed-loop control system is used. The control system senses the spacing between the read/write head and the disc surface, compares the sensed spacing to a desired spacing, and adjusts the voltage applied to the shear transducer to reduce the difference between the actual and desired spacing.

摘要： A slider is provided for actively controlling a fly height of the slider relative to a data storage disc during operation of a data storage system. The slider includes a slider body having front and back surfaces, a length and a crown curvature on the front surface along the length. The slider also includes first and second elongated rails which are positioned on the front surface along the length of the slider body and form first and second bearing surfaces. Each bearing surface includes a leading portion, a trailing portion and a waist portion, wherein the waist portion is wider than the leading and trailing portions and has a maximum width within a middle half of the length of the slider body. A deformable material is positioned on the slider body having a dimension that is changeable in response to an electrical control signal applied in a deformable material, wherein a change in the dimension causes a change in the crown curvature.

摘要： A magnetic data transducing head slider is provided with a transversely extended crossbar or other barrier near the leading edge. The barrier is deposited onto the air bearing surface of the slider using photolithographic techniques that enable precise determination of the barrier dimensions and the barrier set-back from the leading edge. The barrier set-back, width and thickness can be selected to control the transducer flying height and the pitch of the slider relative to the data recording surface of a magnetic disk when the slider is aerodynamically supported relative to the disk. The barrier also acts as a shield to minimize particulate contamination.

摘要： A slider is used for supporting a transducing head proximate a rotating disc. The slider includes a primary air bearing having a disc opposing face bounded by a leading edge and a first trailing edge. An air bearing surface is defined on the disc opposing face. The slider further includes a secondary air bearing having a disc opposing face bounded by a front edge and a second trailing edge. The air bearing surface is defined on the disc opposing face. The air bearing surface has a pad proximate the second trailing edge wherein the transducing head is located on the pad. An interface connects the secondary air bearing to the primary air bearing and the interface displaces the transducing head vertically with respect to the primary air bearing to maintain head media spacing (HMS) between the transducing head and the disc substantially constant as the slider flies above the disc.
