    摘要: A magnetic tape recording module having electrical lapping guides located within and adjacent to an array of magnetic read/write elements. Electrical leads connected with the electrical lapping guides are buried deep within the head build, close to the substrate so that they can pass beneath the electrical leads of the read/write elements without any capacitive coupling between the electrical lapping guide leads and the read/write element leads. The presence of the electrical lapping guides within and adjacent to the read/write element leads provides much more accurate control of read/write element stripe height during lapping.

    摘要: The embodiments of the present invention relate to a method for forming a magnetic read head with pinned layers extending to the ABS of the read head and magnetically coupled with an antiferromagnetic layer that is recessed in relation to the ABS of the read head. Portions of the antiferromagnetic layer and a magnetic layer that are extending to the ABS are removed, exposing a shield. A shielding material is formed on the exposed shield and a seed layer is formed on the shield and on or over a portion of the remaining antiferromagnetic layer. A pinned layer structure is formed on the seed layer and the magnetic layer.

    摘要: A magnetic read sensor having improved pinning and reduced area resistance. The sensor has pinned magnetic layer that extends beyond the functional stripe of the sensor to improve magnetic pinning. The free layer has a magnetic portion that extends to the functional stripe height and a non-magnetic portion that extends beyond the functional stripe height. The sensor may have an end point detection layer located between the magnetic pinned layer and the magnetic free layer.

    摘要: A magnetic slider for magnetic data recording constructed by a process that allows for careful control of seed layer and overcoat thickness. The slider is treated by a process that result in surface pits and scratches. A refill layer is used to fill in the pits and scratches, the refill layer being constructed of a material that does not include Si or carbon. An angled ion beam etching can be used to remove portions of the refill layer that extend outside of the pits and scratches. Then, a seed layer comprising Si and a protective layer comprising C are deposited over the surface. Because the refill layer does not contain either of Si or C, the thickness of the seed layer and carbon overcoat can be acurately measured and controlled, without the refill layer being mistaken for seed or overcoat material.

    摘要: A method for forming a protective overcoat onto a tape bearing surface of a tape head used for magnetic tape recording. In order to ensure optimal surface tension and liftoff properties of the ink mask, the tape bearing surface is treated with a first application of ethanol, followed by an application of polydimethylsiloxane, followed by a second application of ethanol. After this treatment an ink mask can be printed onto the tape bearing surface so as to form a mask having an opening over the location of the magnetic transducer. An etching can then be performed followed by the deposition of a protective coating such as alumina.
