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 cathode-ray tube according to the present invention has on the inner surface of the funnel section of the body thereof a laminated layer comprising a first layer of black material, a metal backing layer and a second layer of black material.According to the configuration of the cathode-ray tube of the present invention, stray light reflected within the body of the cathode-ray tube is absorbed by the first layer of black material on the inner surface of the funnel, while stray light reflected off the inner surface of the funnel is absorbed by the second layer of black material. This makes it possible to reduce the amount of stray light incident upon the effective screen area of the panel section.

A display driving apparatus for outputting control signals to a number of driver integrated circuits (ICs). The plurality of driver ICs are connected in a cascade manner such that, when a first control signal is input to a first driver IC, a transmission signal corresponding to the first control signal is transmitted to a subsequent driver IC using a cascade method. The display driving apparatus includes a restoration signal generation unit for generating restoration signals with respect to the first control signal and transmission signals of the number of driver ICs; an error detection unit for detecting an abnormal driver IC that does not operate normally from among the plurality of driver ICs; and a restoration signal output unit for outputting a restoration signal to the abnormal driver IC.

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.

An optically assisted magnetic recording head causes light to be efficiently incident on a near-field light generating element and is thereby capable of efficiently generating near-field light. The optically assisted magnetic recording head, according to one embodiment, has a waveguide and a thin metal film. The waveguide has a core and a clad at least partially surrounding the core and serves as near-field light generating device. The core has a plate-shaped portion that has a small width and protrudes from an edge of the core. The edge of the core is located on the air bearing surface side. The thin metal film is provided on an upper portion and side portions of the plate-shaped portion to cover the edge of the core at the air bearing surface side. Other systems and methods are disclosed as well to achieve efficient incident light on a near-field light generating element.
