摘要:
Embodiments of the invention provide a perpendicular magnetic recording head that causes the difference between a physical track width and an effective track width to be small. Sides of a main pole are made concave with the concave vertex on each side located close to a trailing edge of the main pole.

Disclosed is an agitating device (3) to be disposed in a batch-type vessel or the like. The agitating device (3) has an upper cover plate (5), a bottom cover plate (6), an impeller (7), an inner screen member (8), and first and second outer screen members (9, 10). When a mixed liquid including a dispersoid and a dispersion medium passes through liquid communication holes (19) of the inner screen member (8) and liquid communication holes (22, 25) of the outer screen members (9, 10) during the course where it flows outward from the impeller (7) to get out of an interplate space, the circumferential component of the flow vector of the mixed liquid is mostly eliminated to allow the mixed liquid to have substantially only the radial component. This prevents the generation of vortexes so as to apply a sufficiently high shearing force to the mixed liquid to effectively prevent the formation of macro bubbles in the mixed liquid.

A 3-dimensional operation input apparatus, a control apparatus, a control system, a control method, and a handheld apparatus are provided with which planar operations are possible without an increase in the number of components. An input apparatus includes an angular velocity sensor unit and an acceleration sensor. A threshold value is set to angular velocity values detected by the angular velocity sensor unit. Depending on whether the angular velocity values are smaller than the threshold value and whether at least one of acceleration values is larger than a threshold value, a switch can be made between a planar operation mode and a 3-dimensional operation mode. Therefore, a switch can be made between the planar operation mode and the 3-dimensional operation mode without having to use a sensor other than the acceleration sensor and the angular velocity sensor without increasing the number of components.

Embodiments of the invention provide a thin film magnetic recording head that can reduce the round portion of the track restriction part of the main pole and has excellent track width accuracy, as well as its fabrication method. In one embodiment, the main pole is etched in the following three processes. (1) An ion beam is injected into the substrate at an angle of about 50°±20° while vibrating the substrate horizontally within a range of about ±(30° to 150°) in a reference direction in which the ion beam is oriented from the medium to the air bearing surface. (2) The ion beam is injected into the substrate at an angle of about 60°±20° while vibrating the substrate around a predetermined angle of about 90° to 135° from a direction in which the ion beam is oriented from the medium to the air bearing surface. (3) The ion beam is injected into the substrate at an angle of about 60°±20° while vibrating the substrate horizontally at a predetermined angle within about ±45° around a predetermined angle within about −90° to −135° from a direction in which the ion beam is oriented from the medium to the air bearing surface.

The present invention is directed to carrying out a high density magnetic recording to a material having a large coercive force by perpendicular magnetic recording head.By giving a patterning onto a soft magnetic under layer of a perpendicular two-layer recording media in sync with a period of a recording bit, a magnetic field from a write head can be allowed to converge to a soft magnetic column. Therefore, a magnetization reversal of the magnetic recording media material having a large anisotropic constant becomes possible, and then a high density magnetic recording can be achieved.

摘要:
A magnetic head for perpendicular recording in which a reduction of an interval between a main pole and a read element is attained by suppressing the phenomenon due to a magnetic field from the main pole entering a read shield and thereby output of the read head being varied. In one embodiment, the shield nearer the main pole of the read head is formed in the three-layer structure of the magnetic layer/non-magnetic layer/magnetic layer.
