摘要： A fiber-optic coil for use as the sensor loop of a fiber-optic gyroscope includes a first optical fiber segment wound as radially successive coiled layers around a coil bobbin in a first region thereof, and a second optical fiber segment wound as radially successive coiled layers around the coil bobbin in an axially adjacent second region thereof. The first and second optical fiber segments are joined to each other through a longitudinal middle portion, which is positioned in the radially innermost coiled layers of the first and second optical fiber segments adjacent to a longitudinal center of said coil bobbin. Each of the first and second optical fiber segments is wound in alternate axial directions in the radially successive coiled layers. The first and second optical fiber segments may be integrally joined to each other by the longitudinal middle portion, or may be separate from, but joined to, each other by a depolarizer across the longitudinal middle portion.

摘要： An optic rotation sensing apparatus includes a light source emitting light. The light emitted from the light source is transmitted to a sensing loop which provides a phase difference between opposite-direction light waves in response to a rotation. Return light outputted from the sensing loop is transmitted to a photodetector. A device modulates a phase of light propagating in the sensing loop. Another device depolarizes light propagating in the sensing loop. The invention further controls and processes an output signal representing the output of the photodetector at a phase at which a level of an AM noise component of the output signal is minimized.

摘要： A magnetic head slider suitable for a disk drive measuring 1.8 inches or less in disk size incorporates preventive measures against the decreases in lifting force that occur in small sliders with a slider width of 0.8 mm or less. The present invention improves the inclination margins of the flying slider in a rolling direction at the lowest flying point, and achieves low flying height and stable flying. The slider is constructed with stepped surfaces on the slider's leading-side flying surface formed up of shallow-grooved surfaces and a deep-grooved surface so that a trailing-side width W2 between the stepped surfaces is smaller than a leading-side width W1.

摘要： Embodiments of the invention provide solutions to a problem, in which a reduced peripheral speed resulting from a trend toward a magnetic disk having a smaller diameter makes it more and more difficult to achieve a lifting force that allows a magnetic head slider to fly stably. According to one embodiment, in a magnetic head slider comprising a leading edge, a trailing edge, and an air bearing surface, the air bearing surface includes a plurality of leading side rail surfaces, a trailing side rail surface disposed in the same plane as the leading side rail surfaces and having a magnetic head mounted thereon, a stepped bearing surface having a predetermined depth δ1 from the leading side rail surface, and a negative-pressure groove surface having a depth δ2 from the leading side rail surface, the depth δ2 being even deeper than the stepped bearing surface. The leading side rail surfaces include first stepped surfaces having a predetermined height h1 and second stepped surfaces having a predetermined height h2 from the first stepped surfaces, the first stepped surfaces and the second stepped surfaces having continuity in a longitudinal direction of the magnetic head slider.

摘要： A magnetic disk unit includes a magnetic disk attached to a spindle so as to be rotatable, a slider having a magnetic head for reading/writing data onto/from the magnetic disk, a suspension for providing the slider with a predetermined load, and an actuator arm for positioning the slider attached to the suspension on the magnetic disk. A first pad including the magnetic head and second pads including no magnetic heads are disposed on an air bearing surface of the slider. During rotation of said magnetic disk, a part of the first pad keeps in contact with the magnetic disk. A load point of the suspension with respect to the slider is positioned between a leading edge of the slider and a position located at a distance equivalent to substantially 0.42 times a whole length of the slider from the leading edge of the slider.
