摘要： A write head including a bearing surface and a write pole having a front surface that forms a portion of the bearing surface. The front surface has a leading edge, a trailing edge and side edges connecting the leading and trailing edges. The write head also includes side shields proximate to the side edges of the write pole, and a trailing shield over the write pole and the side shields. A trailing shield-write pole gap is present between the trailing edge and the trailing shield, and a trailing shield-side shield gap is present between the trailing shield and the side shields. The trailing shield side shield gap is substantially less than the trailing shield-write pole gap.

摘要： A data writer can be fabricated by constructing a write pole to continuously extend from an air bearing surface prior to depositing a first gap layer to continuously extend from the ABS in contact with a first write pole sidewall. A first side shield protrusion can then be formed on the air bearing surface to be separated from the write pole by the first gap layer. A second gap layer may be deposited to continuously extend from the first side shield protrusion along the first write pole sidewall to define a dielectric region on which a second side shield protrusion is formed with the second side shield protrusion separated from the write pole by the first and second gap layers and the first and second side shield protrusions each cantilevered from a common side shield body.
摘要翻译：数据写入器可以在沉积第一间隙层之前从空气轴承表面构造一个连续地从第一写入磁极侧壁接触的ABS连续地延伸的写极制造。然后可以在空气轴承表面上形成第一侧面屏蔽突起，以通过第一间隙层与写入极分离。可以沉积第二间隙层，以从第一侧屏蔽突起沿着第一写磁极侧壁连续延伸，以限定形成第二侧屏蔽突起的电介质区域，其中第二侧屏蔽突起与写极分离第一侧屏蔽突起和第二间隙层以及从公共侧屏蔽体悬臂的第一和第二侧面屏蔽突起。
