    摘要: A method and system for providing a PMR pole in a magnetic recording transducer including an intermediate layer are disclosed. The method and system include providing a mask on the intermediate layer. The mask includes a line having at least one side. A hard mask layer is provided on the mask. At least a portion of the hard mask layer resides on the side(s) of the line. At least part of the hard mask layer on the side(s) of the line is removed. Thus, at least a portion of the line is exposed. The line is then removed, providing an aperture in the hard mask corresponding to the line. The method also includes forming a trench in the intermediate layer under the aperture. The trench top is wider than its bottom. The method further includes providing a PMR pole, at least a portion of which resides in the trench.

    摘要: A manufacturing method of a circuit board is provided. A metal core is provided. A conductive layer is formed on each of some carriers. The carriers and dielectric layers are laminated at both sides of the metal core to form a stacked structure. Each of the dielectric layers is located between the corresponding carrier and the metal core, and a portion of the conductive layer is embedded in the corresponding dielectric layer. Then, the carriers are removed. A blind via and/or a through via are/is formed in the stacked structure to connect the corresponding conductive layer and the metal core and/or connect the conductive layers at both sides of the metal core, wherein the through via penetrates the metal core. The conductive layer on a surface of the dielectric layer is removed.

    摘要: A read head for a disk drive and a method of fabricating the read head with overlaid lead pads that contact the top surface of the sensor between the hardbias structures to define the electrically active region of the sensor are described. The invention deposits the GMR and lead layers before milling away the unwanted material. A photoresist mask with a hole defining the active area of the sensor is preferably patterned over a layer of DLC that is formed into a mask. A selected portion of the exposed lead material is then removed using the DLC as a mask defining the active region of the sensor. A photoresist mask pad is patterned to define the full sensor width. The excess sensor and lead material exposed around the mask is milled away. The layers for the hardbias structure are deposited.

    摘要: A read element for a tape drive system is disclosed. The read element generally comprises a magneto-resistive sensor electrically coupled to first and second leads and at least one electrically conductive magnetic shield proximate the magneto-resistive element. A resistor is electrically connected to the conductive magnetic shield and to one or more of the first and second leads. The resistor is disposed between the first and second leads. The resistor continuously discharges electric charge that builds up on the conductive magnetic shield. The resistor typically has a resistance that is large enough to protect against noise due electrical shorting of the conductive magnetic shield and small enough to prevent a build-up of electric charge on the shield.
