    摘要： In order to improve a consistent data track during writing to a storage medium, a plurality of read sensors are affixed to a transducer head. In one implementation, the transducer head includes multiple read sensors placed up-track of the write pole. In another implementation, the transducer head includes at least one read sensor placed up-track of the write pole and at least one read sensor placed down-track of the write pole. Each position of the multiple read sensors relative to the write pole may be unique. One or more read signals of selected read sensors are used to determine the read location and therefore the write pole location relative to the storage medium.

    摘要： A magnetic device includes a read sensor, a writer and a synchronization sensor. The magnetic device is configured for writing information to and reading information from a magnetic medium that includes a plurality of discrete magnetic bits. The writer includes a write element, a first return element magnetically coupled to the write element, and a second return element magnetically coupled to the write element. The write element is positioned in between the first and second return elements. The synchronization sensor is located adjacent to the write element of the writer in a closely spaced arrangement, and is configured to generate a signal as a function of a sensed magnetic bit. The signal is used to position the writer element relative to the sensed magnetic bit.

    摘要： A method of fabricating a magnetic device is described. A mask removing layer is formed on a layered sensing stack and a hard mask layer is formed on the mask removing layer. A first reactive ion etch is performed with a non-oxygen-based chemistry to define the hard mask layer using an imaged layer formed on the hard mask layer as a mask. A second reactive ion etch is performed with an oxygen-based chemistry to define the mask removing stop layer using the defined hard mask layer as a mask. A third reactive ion etch is performed to define the layered sensing stack using the hard mask layer as a mask. The third reactive ion etch includes an etching chemistry that performs at a lower etching rate on the hard mask layer than on the layered sensing stack.
