摘要： A perpendicular magnetic recording (PMR) head with single or double coil layers has a small write shield stitched onto a main write shield. The stitched shield allows the main write pole to produce a vertical write field with sharp vertical gradients that is reduced on both sides of the write pole so that adjacent track erasures are eliminated. From a fabrication point of view, both the main pole and the stitched shield are defined and formed using a single photolithographic process, a trim mask and CMP lapping process so that the main shield can be stitched onto a self-aligned main pole and stitched shield.

摘要： A magnetic recording head for use in perpendicular magnetic recording having a design that allows the write coil to be manufactured by a damascene process for increased coil pitch and reduced coil resistance. The magnetic write head includes a photoresist dam structure that allows a hard baked photoresist to be formed that does not extend to the air bearing surface (ABS). Since the photoresist dam prevents the hard baked photoresist from reaching the ABS, the damascene process, in which the hard baked photoresist remains in the finished write head, can be used to produce the write head. The use of such a damascene process advantageously allows the space between the coil turns to be reduced, which maximizes the number of turns that can be used and also maximizes the number width to which the coil turns can be constructed, thereby minimizing the electrical resistance of the write coil.
摘要翻译：一种用于垂直磁记录的磁记录头，其具有允许通过镶嵌工艺制造写入线圈以增加线圈间距并减小线圈电阻的设计。磁写头包括光致抗蚀剂阻挡结构，其允许形成不延伸到空气轴承表面（ABS）的硬烘烤光致抗蚀剂。由于光致抗蚀剂防止了硬烘烤的光致抗蚀剂到达ABS，因此可以使用其中硬烧结光致抗蚀剂保留在完成的写头中的镶嵌工艺来产生写头。使用这种镶嵌工艺有利地减小了线圈匝之间的空间，这使得可以使用的匝数最大化，并且还使构造线圈匝数的数量最大化，从而最小化电阻写线圈。
