  • Patent number: 6496334
    Abstract: In at least one embodiment, the apparatus of the invention is a read sensor comprising a shield, a sensor element, an extra shield between the shield and the sensor element, an extra gap between the shield and the sensor and adjacent the extra shield, and a gap layer between the sensor element and the extra shield. The sensor element is positioned in a sensor layer. With the extra shield adjacent to the sensor element and separated by only the relatively thin gap layer, high areal recording density and excellent instability of the sensor element is obtained. At the same time, by fabricating the extra shield to be not significantly wider than the sensor element, the potential for shorting is minimized by placing both the gap and the thicker extra gap between the sensor lead elements and the shield.
