摘要： A method for manufacturing a magnetoresistive sensor that results in the sensor having a very flat top magnetic shield. The process involves depositing a plurality of sensor layers and then depositing a thin high density carbon CMP stop layer over the sensor layers and forming a mask over the CMP stop layer. An ion milling is performed to define the sensor. Then a thin insulating layer and magnetic hard bias layer are deposited. A chemical mechanical polishing is performed to remove the mask and a reactive ion etching is performed to remove the remaining carbon CMP stop layer. Because the CMP stop layer is very dense and hard, it can be made very thin. This means that when it is removed by reactive ion etching, there is very little notching over the sensor, thereby allowing the upper shield (deposited there-over) to be very thin.

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： Perpendicular-magnetic-recording head with leading-edge taper of a planarized stepped-pole layer having greater recess distance than a flare point of a main-pole layer. The perpendicular-magnetic-recording head includes a write element including the main-pole layer having the flare point recessed a first distance from a pole tip of the main-pole layer at an air-bearing surface below the air-bearing surface. The write element includes the stepped-pole layer magnetically coupled with the main-pole layer across an interface between the main-pole layer and the stepped-pole layer. The stepped-pole layer has the leading-edge taper recessed a second distance from the pole tip of the main-pole layer at an air-bearing surface below the air-bearing surface. The second distance of the leading-edge taper is greater than the first distance of the flare point. A surface of the stepped-pole layer is planarized with the interface between the main-pole layer and the stepped-pole layer substantially flat over the leading-edge taper.

摘要： A magnetic write head for data recording having a magnetic write pole with a stepped magnetic shell structure that defines a secondary flare point. The secondary flare point defined by the magnetic shell portion can be more tightly controlled with respect to its distance from the air bearing surface (ABS) of the write head than can a traditional flare point that is photolithographically on the main pole structure. This allows the effective flare point of the write head to be moved much closer to the ABS than would otherwise be possible using currently available tooling and photolithography techniques. The write head also includes a non-magnetic spacer layer formed over the magnetic shell structure that is recessed from the ABS by a distance that is greater than that of the magnetic shell portion. A magnetic shield is formed over the magnetic shell and non-magnetic spacer.

摘要： A magnetic write head for perpendicular magnetic recording. The write head has a secondary flare point defined by magnetic structures that extend from the sides of the write pole, but not over the trailing edge of the write pole. The magnetic structures each have a front edge that defines the secondary flare point. By constructing the magnetic structures so that they only extend from the sides of the write pole and not over the write pole, they can be formed by electroplating, while leafing the mask structure (used to define the write pole) still intact, thereby greatly simplifying manufacture and preventing damage to the write pole during manufacture.

摘要： Described are a device and system to transmit data to or receive data from one or more data lane interfaces. Each data lane interface may be capable of transmitting a serial data signal to or receiving a serial data signal from a data lane in a device-to-device interconnection. An effective data rate may be varied based, at least in part, upon a number of the data lane interfaces actively transmitting a serial data signal to or receiving a serial data signal from the device-to-device interconnection.

摘要： Heads for perpendicular recording using a floating-trailing shield are described. The floating-trailing shield is separated from the main pole piece by a layer of non-magnetic material along its entire length and the air bearing surface of the floating-trailing shield is substantially larger than that of the main pole piece. The reluctance between the trailing shield and the underlayer in the recording medium is made so low that both are at the same magnetomotive force (or potential), so that no direct connection is needed between the floating-trailing shield and the yoke. When the head is used in a storage system with a magnetic recording medium with a soft underlayer, the floating-trailing shield is, in effect, magnetically shorted to the return pole piece during recording. In one embodiment the floating-trailing shield wraps around the sides of the main pole piece.
