Abstract: In a thin film magnetic head comprising a magnetoresistive sensing element (MRE) located inwardly from the head face, a first section of a broken flux guide extending inwardly from the head face to overlie one peripheral edge portion of the MRE, and a second section overlying an opposite peripheral edge portion of the MRE, the space overlying the MRE between the flux guide sections is filled with a poller such as a photoresist, providing a smooth surface for a test/bias conductor, reducing shorts due to inadequate step coverage, and providing mechanical stress relief, leading to improved stability of the MRE.
Abstract translation: 在包括位于头部表面内侧的磁阻感测元件（MRE）的薄膜磁头中，从磁头表面向内延伸以覆盖MRE的一个周边边缘部分的断开的磁通引导件的第一部分和覆盖在MRE的一个外围边缘部分上的第二部分 MRE的相对的外围边缘部分，在通量引导部分之间覆盖MRE的空间被诸如光致抗蚀剂的抛光器填充，为测试/偏置导体提供平滑的表面，减少由于不充分的步骤覆盖而引起的短路，并且提供 机械应力消除，导致MRE的稳定性提高。

Abstract: A process for fabricating a negative pressure slider is disclosed which briefly comprises the steps of: (a) applying a dry negative photoresist layer to the surface of the slider; (b) positioning a mask having alignment marks which are too narrow to be resolved during exposure and development to pattern the photoresist layer to expose the portions of the flying surface of the slider to be milled by an ion milling process; (c) ion milling the slider wherein the patterned photoresist layer protects the flying surface of the slider while the negative pressure cavities of the slider are being milled; and (d) removing the remaining portions of the photoresist layer once the negative pressure cavities have been milled.

Abstract: A magnetoresistive sensor (10) having permanent magnet stabilization includes a magnetoresistive layer (12), at least one permanent magnet (14a or 14b), and first and second current contacts (16a and 16b). The magnetoresistive layer (12) has an active sensing region (18) having a first thickness, and at least one under layer region (26a or 26b), with each under layer region (26a or 26b) having a second thickness that is less than the first thickness. Each permanent magnet (14a or 14b) is formed upon an under layer region (26a or 26b) of the magnetoresistive layer (12), and the first and second contacts (16a and 16b) are electrically coupled to the active region (18).

Abstract: A magnetic head is manufactured by depositing a layer of spacer material onto the facing surfaces of the magnetic cores; the thickness of each layer being approximately one-half the length of the intended gap and the thicknesses of both layers together being approximately equal to the thickness (length) of the gap. A layer of bonding glass is deposited onto the surfaces of the spacer layers and the cores are pressed together at an elevated temperature to fuse the glass layers and extrude most of the glass.

Abstract: A vertical recording head includes a W-shaped core, a substrate carrying a thin film probe supported in one slot of the core, and a shield coil wound in the slots to hold the substrate and assemblage together. A non-magnetic cap forms the surface of the head over the cap, with the arrangement being such that the probe extends through the cap so the magnetic gap is as small as possible.
