摘要： PROBLEM TO BE SOLVED: To provide a smear-removing method for removing smear of a manufactured thin-film magnetic head.
SOLUTION: The smear removing method is performed to a thin-film magnetic head including an MR effect element for reading data having two electrode layers sandwiching an MR effect laminated body as a magneto-sensitive portion therebetween. The method includes the step of applying a stress voltage less than the breaking voltage of the MR effect element between the two electrode layers to burn off smear. In the method, it is preferable that the stress voltage is applied while the electric resistance or the output voltage of the MR effect element is measured, and the stress voltage is increased until the value of the electric resistance or the output voltage reaches an upper limit specified value specified from the value of the electric resistance or the output voltage in a normal case where the smear is not present.

摘要： PROBLEM TO BE SOLVED: To make a recording head part not to be brought into contact with a hard disk while assuring the magnetic space of a reproducing head part as to a magnetic disk device which is represented by a hard disk drive and a thin film magnetic head used in the magnetic disk device.
SOLUTION: It becomes possible to make the recording head part not to be brought into contact with the hard disk while assuring the magnetic space of the reproducing head part by providing a level difference only at the recording head part on the head surface on the ABS surface of a head slider. Moreover, even when the recording head part is brought into contact with the hard disk, it is possible to make probability in which the contact gives damage, such as a crack to a GMR element and which causes the reduction and noise of a reproduced output small by giving space between a recording head and a reproducing head in a track width direction.

摘要： PROBLEM TO BE SOLVED: To provide a thin film magnetic head which can enhance the magnetic field gradient and the magnetic field intensity as much as possible in a perpendicular magnetic field.
SOLUTION: The magnetic main pole layer 15 is retreated from the write shield layer 40. Since the overlapping area LA for the main magnetic pole layer 15 and the write shield layer 40 to overlap each other rather is made smaller than in the case the main magnetic pole layer 15 is not retreated from the write shield layer 40, the magnetic flux J1 from the main magnetic pole layer 15 to the recording medium 60 is relatively increased and the magnetic leakage flux J2 from the main magnetic pole layer 15 to the write shield layer 40 is relatively decreased.
