Abstract: A method for manufacturing a magnetic write head having a write pole with a tapered leading edge and a tapered trailing edge. The method includes forming a non-magnetic bump player over a surface, forming a mask over the non-magnetic bump layer and performing a first ion milling to form a tapered back edge on the non-magnetic bump layer. A magnetic write pole material is then deposited over the surface and over the non-magnetic bump layer. Then a non-magnetic step structure is formed over the magnetic write pole material and an ion milling is performed to form a taper on the upper surface of the write pole. The write pole lateral dimensions can then be defined, and a non-magnetic bump formed over the tapered portion of the upper surface of the write pole. Another ion milling can then be performed to extend the taper of the surface of the write pole.

Abstract: Methods and apparatus for serial channel operation are disclosed. An N+1-level signaling scheme is used to transmit N staggered but overlapping NRZ sub-sequences concurrently on a serial channel. Each sequence has a bit rate R and an essential bandwidth of R Hz. The combined bit rate of the channel is N×R, but due to a lack of correlation between the sub-sequences, the essential bandwidth remains approximately R Hz. The signaling scheme also contains redundancy that allows some errors to be detected and/or corrected. Other embodiments are also described and claimed.

Abstract: A method for patterning a wafer using a phase shifting photolithography that can produce a critical symmetrical 2-dimensional structure such as a magnetic write pole of a magnetic write head. In one aspect of the invention, a photolithographic mask has an opaque portion with narrow, transparent phase shifting regions at either side of the opaque portion. A non-phase shifted region extends beyond the narrow phase shifted portion at either side of the structure. The phase shifted regions are symmetrical about the opaque region so that the image produced on the wafer is completely symmetrical. In another aspect of the invention, a phase shifted region in formed in a transparent medium with non-phase shifted regions at either side of the phase shifted region. The transition between the phase shifted region and non-phase shifted region alone defines a pattern on the wafer, without the need for an opaque structure on the mask.

Abstract: A method for forming a magnetic write head using a damascene process that does not form voids in the magnetic structure. An opening is formed in an alumina layer, the opening being configured to define a trench. Then a first layer of magnetic material is deposited into the trench. A CMP process is then performed to remove any voids that have formed in the first magnetic layer. Then a second layer of magnetic material is deposited over the first layer of magnetic material. In another embodiment of the invention, a opening is formed in the alumina layer, and a first layer of magnetic material is electroplated into the opening. A thin layer of non-magnetic material is then deposited, and a second layer of magnetic material is deposited over the thin layer of non-magnetic material. The thin layer of alumina advantageously provides a laminate structure that avoids data erasure.

Abstract: A magnetic write head having write pole and a wrap-around-trailing magnetic shield having side portions that are separated from the write pole by tapered non-magnetic side gap layers. The tapered non-magnetic side gap layers provide a non-magnetic side gap width that increases with increasing distance from the ABS, thereby providing optimal protection against adjacent track interference at the ABS while minimizing write field loss to the shield in regions away from the ABS.
