    摘要: A method for fabricating a magnetic head with a trapezoidal shaped pole piece tip is described. The body of the main pole piece is deposited, then one or more layers for the pole piece tip are deposited. A bed material is deposited over the pole piece tip material. A void is formed in the bed material over the area for the pole piece tip. The void is filled with an ion-milling resistant material such as alumina preferably using atomic layer deposition or atomic layer chemical vapor deposition. The excess ion-milling resistant material and the bed material are removed. The result is an ion-milling mask formed over the area for the pole piece tip. Ion milling is then used to remove the unmasked material in the pole piece tip layer and to form a beveled pole piece tip and preferably a beveled face on the main pole piece.

    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.

    摘要: A method in a KVM switch system for interacting with the user to switch computer ports using a touch panel device having a touch-sensitive screen is described. The system allows a user to accomplish port switching by “drawing” a symbol (such as an Arabic number) representing a port number on the touch screen, coupled with other actions, such as one or more touches of the screen, an action using another input device such as a mouse, keyboard, buttons, etc., to confirm the port number input.

    摘要: A method and system for providing a pole of magnetic transducer having an air-bearing surface (ABS) are described. Leading shield and planarization stop layers are provided. Portions of the planarization stop and shield layers distal from the ABS location are removed, providing a depression forming a bevel. The bevel has an angle greater than zero and less than ninety degrees. An intermediate layer having a top surface substantially perpendicular to the ABS location is provided. Part of the intermediate layer is removed, forming a trench having a bottom corresponding to the leading shield and a location and profile corresponding to the pole. A nonmagnetic layer is provided at least partially in the trench. The pole with a leading edge bevel corresponding to the bevel is provided in the trench. A capping layer covering the pole is provided, at least part of the intermediate layer removed, and a wrap-around shield provided.
