摘要： An integrated read/write perpendicular recording head facilitates the use of magnetic storage media having a high magnetic recording density and high data rates. The use of a perpendicular write portion provides adequate space between the main and opposing poles for a read element and associated electrical contacts therebetween. The use of a differential dual spin valve as a read element eliminates the need for magnetic shielding of the read element. Such a structure permits the read element and main write pole to be close together, thereby minimizing seek time, and permitting rapid transition from read to write operations, and vice versa.

摘要： The invention is directed toward a lapping apparatus and method for accurately obtaining the height of a magnetoresistive (MR) element of a magnetic head during a lapping process. The apparatus includes a source for inducing a magnetic excitation field, and a current source for applying a sense current to a prepatterned photolithographically formed MR element. A sensor monitors the resistance of the MR element in response to variations in the magnetic excitation field, and controls the lapping process in response to the monitored resistance of the MR element. In one embodiment, the MR element includes a GMR formed of a stack of parallel MR layers and operates either in a CPP (Current-Perpendicular-to-the Plane) mode or in a CIP (Current-In-the Plane) mode. In a particular embodiment, the magnetic excitation field is generated by a conductor formed on the magnetic head.
