Phenylacetamide compound and pharmaceutical containing same

The invention provides a method for fixing up the deterioration of a magneto-resistive effect device. A hard disk system is provided in it with a head heating means for heating a thin-film magnetic head, and by that head heating means, a defective site of the magneto-resistive effect device, which occurs as the hard disk system is in operation and is confined in a quasi-stable state, is fixed up in such a way as to return back to its own normal stable state. Thus, the deteriorated site of the magneto-resistive effect device (reproducing device) in the thin-film magnetic head, which is caused by the so-called thermal asperity as the hard disk system is in operation, is fixed up while it remains built in the hard disk system, i.e., without dismantling the hard disk system.

Method of repairing the deterioration of magneto-resistive effect device

A thin film magnetic head includes: a magneto resistance effect film of which electrical resistance varies corresponding to an external magnetic field; a pair of shields provided on both sides in a manner of sandwiching the MR film in a direction that is orthogonal to a film surface of the MR film; an anisotropy providing layer that provides exchange anisotropy to a first shield of the pair of shields in order to magnetize the first shield in a desired direction, and that is disposed on the opposite side from the MR film with respect to the first shield; and side shields that are disposed on both sides of the MR film in a track width direction and that include soft magnetic layers magnetically connected with the first shield.

A thin film magnetic head includes; an MR film that includes a pinned layer of which a magnetization direction is pinned, a free layer of which a magnetization direction varies, and a spacer that is disposed therebetween; a pair of shields that are disposed on both sides sandwiching the MR film in a direction orthogonal to a film surface of the MR film; and an anisotropy providing layer that provides anisotropy to a first shield so that the first shield is magnetized in a desired direction, and that is disposed on an opposite side from the MR film with respect to the first shield. The MR film includes a magnetic coupling layer that is disposed between the first shield and the free layer and that magnetically couples the first shield with the free layer.

A method of manufacturing a magnetic head, including a magneto resistance effect (MR) element that reads a magnetic recording medium, is disclosed. A multilayer film is formed on a shield layer. Unnecessary portions of the multilayer film are removed from both sides of the MR element in a first direction orthogonal to a lamination direction of the multilayer film and parallel to the MR element surface facing the magnetic recording medium. An insulating layer is formed on a surface exposed by removal of the unnecessary portions. An integrated soft magnetic layer covering both sides of the MR element in the first direction and an upper side of the MR element is formed, thereby configuring a second shield layer. An anisotropy application layer is formed on the second shield layer, thereby providing exchange anisotropy to the soft magnetic layer, and magnetizing the soft magnetic layer in a predetermined direction.

Method of manufacturing a magnetic head including shield layers which surround a MR element

Provided is a smear-removing method that can remove smear of a manufactured thin-film magnetic head. The 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 multilayer as a magneto-sensitive portion therebetween. The method comprises the step of applying a stress voltage less than a 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 an electric resistance or an 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 a value of an electric resistance or an output voltage in a normal case where smear is not present.

A composite type thin-film magnetic head is provided, which comprises: a write head element; a pair of terminal pads for the write head element; a pair of lead conductors for the write head element, electrically connecting the write head element to the pair of terminal pads for the write head element; a read head element; a pair of terminal pads for the read head element; and a pair of lead conductors for the read head element, electrically connecting the read head element to the pair of terminal pads for the read head element. The pair of lead conductors for the write head element and the pair of lead conductors for the read head element are formed into patterns that have no overlapped portions with each other through only an insulating layer.
