Abstract: A magnetic recording and reproducing apparatus, including a probe made of a ferromagnetic film movable relative to a magnetic recording medium while having a distal end facing the magnetic recording medium; a head section having a recording element for recording a signal on the magnetic recording medium and a reproducing element including at least a probe for reproducing a signal recording on the magnetic recording medium; and a head slider for mounting the head section. The head slider includes a slider section having a slider surface facing the magnetic recording medium and configured to receive a hydrodynamic force generated by a dynamic effect of a gaseous flow caused by rotation of the magnetic recording medium, and a head support, coupled to the slider section, for supporting the head section such that the reproducing element contacts the magnetic recording medium, the head support having a mass smaller than that of the slider section, an area of a surface of the head support facing the magnetic recording medium being smaller than an area of the slider surface. The apparatus also includes a DC voltage application device for applying a DC voltage between the probe and a recording layer; and a device for detecting a tunnel current flowing between the distal end of the probe and the recording layer through a non-magnetic layer by application of the DC voltage, thereby reproducing a signal recorded on the magnetic recording medium.

Abstract: A magnetic write head having a magnetic cross yoke arranged to provide a cross magnetic field in a pole tip region of the magnetic head. The cross field, which is perpendicular to the magnetization of write pole, reduces the switching time of the write field, thereby increasing the speed with which the write head can record data. The write head can be a longitudinal write head or a perpendicular write head. In the case of a perpendicular write, the write head can include a write pole arranged to provide a magnetic write field that emits a magnetic field substantially perpendicular with an Air Bearing Surface (ABS). A magnetic cross yoke is formed having ends that are disposed at opposite sides of the pole tip region of the write pole.

A magnetic cross yoke is formed having ends that are disposed at opposite sides of the pole tip region of the write pole. A magnetic cross field that extends across the pole tip region of the write pole slightly alters the direction of the magnetization of the write pole. If the head is a longitudinal head, it can include first and second magnetic poles separated in the pole tip region by a write gap. The cross yoke can be arranged to produce a cross field that extends across the pole tip region defined by the first and second magnetic poles.

Abstract: A magnetoresistance-effect sensor for use in a magnetic domain detector for reading data recorded on magnetic tapes or in magnetic bubble memories mainly consists of a layer of semiconductor material which carries a layer of ferrimagnetic material on one face and at least one pair of electrodes disposed along an axis OX on the other face, the layer of ferrimagnetic material being placed in proximity to the magnetic data carrier. A magnetic data item thus induces a magnetic field in the layer of semiconductor material in a direction OY perpendicular to the axis OX of the pair of electrodes.
