A ring-shaped glass spacer is configured to be arranged in contact with a magnetic disk in a hard disk drive apparatus. A surface resistivity of a surface of a glass material of the glass spacer at 22 (° C.) is lower than a surface resistivity of an inner portion of the glass material at 22 (° C.).

A glass material of a glass spacer has a surface resistivity of 10.sup.3 to 10.sup.9 (Ω/sq) at 22 (° C.). The surface resistivity of a surface of the glass material of the glass spacer at 22 (° C.) is lower than the surface resistivity of an inner portion of the glass material at 22 (° C.). The glass spacer contains at least one oxide selected from the group consisting of TiO.sub.2, Nb.sub.2O.sub.5, WO.sub.3, and Bi.sub.2O.sub.3, as a glass component.

A data storage device may be configured with a transducing head mounted to a slider. The slider may be suspended above a magnetic data storage medium and have a variable depth region, central rail wall, first wall, and trailing edge wall. The variable depth region continuously contacting a central rail wall from a first wall to a trailing edge wall.

In one implementation, the presently disclosed technology teaches an apparatus with a head attached to an end of a baseplate. The baseplate includes a tilted section that causes a torsion axis of the baseplate to pass near the head. In another implementation, the presently disclosed technology teaches an apparatus with a load beam attached to a baseplate. The apparatus also includes a head attached to an opposite end of the load beam from the baseplate. The baseplate includes a mass-shifted section that causes a torsion axis of the apparatus to pass through the head. In yet another implementation, the presently disclosed technology teaches a method for reducing baseplate resonance amplitude. The method includes shifting a baseplate mass on a suspension toward an adjacent disc surface to move a baseplate torsion axis to pass near a head.
