Method for fabricating magnetic write heads |
摘要 |
A magnetic write head and method for bulk fabrication of the same are provided. A trench is formed in a nonmagnetic substrate. A first magnetically permeable layer is deposited in the trench of the substrate. An optional first insulating layer is deposited in the trench. A conducting circuit is defined in the trench. The conducting circuit creates the magnetic flux. An optional second insulating layer is deposited in the trench. Writer gaps are patterned and then a second magnetic layer is added over the second insulating layer. The substrate is divided to form individual write heads.
