摘要： A logic device is described. The logic device includes magnetic input/channel regions, magnetic sensor region(s), and sensor(s) coupled with the magnetic sensor region(s). Each magnetic input/channel region is magnetically biased in a first direction. The magnetic sensor region(s) are magnetically biased in a second direction different from the first direction such that domain wall(s) reside in the magnetic input/channel regions if the logic device is in a quiescent state. The sensor(s) output a signal based on a magnetic state of the magnetic sensor region(s). The input/channel regions and the magnetic sensor region(s) are configured such that the domain wall(s) may move into the magnetic sensor region(s) in response to a logic signal being provided to the magnetic input region(s). The magnetic input/channel region(s) include FexCoyNizM1q1M2q2, with x+y+z+q1+q2=1, x, y, z, q1, q2 at least zero and M1 and M2 being nonmagnetic.

摘要： In one embodiment of the present invention, a write head includes a P1 pedestal layer, a back gap layer, a coil formed between the P1 pedestal layer and the back gap layer, a hard bake photoresist formed above the P1 pedestal layer, and a hard bake photoresist barrier extending from and on either side of the P1 pedestal layer, wherein the hard bake photoresist barrier acts as a ‘dam’ for the hard bake photoresist to adhere to during manufacturing of the write head.

摘要： A method for fabricating a magnetic head with a trapezoidal shaped pole piece tip is described. The body of the main pole piece is deposited, then one or more layers for the pole piece tip are deposited. A bed material is deposited over the pole piece tip material. A void is formed in the bed material over the area for the pole piece tip. The void is filled with an ion-milling resistant material such as alumina preferably using atomic layer deposition or atomic layer chemical vapor deposition. The excess ion-milling resistant material and the bed material are removed. The result is an ion-milling mask formed over the area for the pole piece tip. Ion milling is then used to remove the unmasked material in the pole piece tip layer and to form a beveled pole piece tip and preferably a beveled face on the main pole piece.
