Abstract: For a slider having convex curvature along its length, or "crown", a method is described for reducing fly height variation due to crown by shifting the peak of the crown toward the leading end, and the resultant slider structure. In a preferred method, peak shifting is accomplished in a slider with symmetrical crown by affixing a suspension to the bonding surface of the slider near the leading end. The bonding process creates a displacement force upon the slider to effect the shift. An alternative approach reshapes a row of sliders prior to rail shaping, e.g., by sand or bead blasting.

Abstract: A process, apparatus, and system are disclosed for inhibiting erroneous control signals due to disruptive electromagnetic signals. In one embodiment, the invention prevents erroneous information writing in a recording device under the effect of background electromagnetic waves. A conductor pattern is formed on a printed wiring board on which wiring constituting a control circuit of a hard disk drive is formed. Background electromagnetic waves are detected by an electromagnetic wave detection circuit. In the case where an electromagnetic wave signal detected by the electromagnetic wave detection circuit exceeds a predetermined power, voltage, or current threshold, a write gate signal is turned off to inhibit a potential write operation.

Abstract: Provided is a technology capable of inhibiting erroneous information writing in a recording device under the effect of background electromagnetic waves. A conductor pattern (7) is formed on a printed wiring board on which wiring constituting a control circuit of a hard disk drive is formed. Background electromagnetic waves are detected by an electromagnetic wave detection circuit (16). In the case where an electromagnetic wave signal level exceeds a predetermined threshold, a write gate signal is turned off to inhibit write operation.
