Abstract: A high throughput method for producing the narrow track width inductive head is also provided, whereby the heads may be manufactured in substantial volumes. The new head may be merged or piggy-backed MR or GMR heads, comprising a first pole piece, P1, and a second pole piece, P2, and is distinctly characterized by write track width is significantly reduced by a preliminary ion milling process before P1 notching is performed. The preliminary step utilizes an ion milling process to trim the write track width, P2B, at an angle between 45 to 85 degrees from the wafer normal. The MR head may then undergo conventional P1 notching.

The second pole tip is formed with a width that defines a track width of the write head. The third pole tip component is formed with top and bottom surfaces wherein the bottom surface interfaces a top surface of the second pole tip component and has a width equal to the track width and wherein the top surface of the third pole tip has a width greater than the track width.

Abstract: To protect the MR read head element from ESD damage during wafer level manufacturing, a lead from the MR element is electrically connected to one or both of the read head element shields during manufacturing. In a preferred embodiment of the present invention, the electrical connection is fabricated in the kerf area between adjacent magnetic heads as they are fabricated upon a wafer substrate. Thereafter, when the magnetic heads are separated by saw cutting through the kerf areas, the electrical connections are thereby removed, such that the MR element electrical leads and the shields are electrically isolated. In an alternative embodiment, one or more of the shields, as well as the MR element leads can also be electrically connected to the substrate upon which the magnetic head is fabricated. In further alternative embodiments, the electrical connection between one or more of the shields and the MR element electrical lead can be fabricated within the magnetic head area, rather than in the kerf area, and a suitable resistance is fabricated into the interconnecting circuit. In this embodiment, the electrical interconnection between the MR element electrical lead and one or more of the shields has a pre-designed electrical resistance and it remains in the magnetic head following fabrication.

Abstract: A magnetic transducer including an electrically conductive shield (ECS) which is disposed between the substrate and first magnetic shield is described. The ECS is preferably embedded in an insulating undercoat layer. The ECS is preferably electrically isolated from the magnetic sensor element and is externally connected to a ground available in the disk drive through the arm electronics. Two alternative ways for connecting the ECS to a ground are described. In one embodiment which is only effective with single-ended input type arm electronics, the ECS is connected to a ground through a via to a lead pad for the read head which is connected to the ground of the arm electronics. In a second and more preferred embodiment a separate lead pad is included on the head to allow the ECS to be connected to electronic or case ground when the head is installed in the arm. The extent of the ECS should be sufficiently large to cover the read head portion of the transducer, i.e., from the edge of the first magnetic shield to the outer edges of the read contact pads, but should preferably not cover the write head pads.

Abstract: The improved process according to the invention prepares samples for subsequent imaging by directing the FIB beam so that its incident angle is not parallel to the planar boundaries between the materials with different etch rates. This nonparallel alignment has the effect of evening out the etch rate, since most of the key beamlets cut more than one type of material. SEM images of the resulting samples are easier to interpret than those produced by the prior art since the obscuring effect of curtaining is reduced. This allows greater accuracy of measurement from the image obtained by an SEM. A method according to a preferred embodiment of the invention is used to prepare a pole piece tip of a magnetic transducer so that the bottom width may be more accurately measured.
