摘要： A compact slider has a reduced area of bearing surfaces, thus substantially decreasing a lifting force obtained through an air bearing characteristic. In one embodiment, a shallowly grooved surface and air bearing surfaces are disposed on an inflow side of a bearing surface of a slider. The air bearing surfaces are connected to each other through a connection air bearing surface. Side shallowly grooved surfaces are respectively disposed rearward of the air bearing surfaces. The side shallowly grooved surface extends up to a point near an outflow end. A center air bearing surface is disposed on the outflow end of the slider. A magnetic head is mounted on the center air bearing surface. A center shallowly grooved surface is disposed on an inflow side of the center air bearing surface. A deeply grooved surface is disposed at a center of the bearing surface. No cutting margins are provided on both sides of the slider. The air bearing surfaces on the inflow side therefore reach end faces in a width direction of the slider.

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： A compact slider has a reduced area of bearing surfaces, thus remarkably decreasing a lifting force obtained by an air bearing characteristic. In one embodiment, a shallowly grooved surface is disposed on an inflow side of a bearing surface of a slider, and a pair of inflow side air bearing surfaces are disposed rearward of and adjacently to the shallowly grooved surface. Side shallowly grooved surfaces are disposed on both sides rearward of the air bearing surfaces in such a manner as to extend near an outflow end. A center air bearing surface is disposed at a center in a width direction at the outflow end of the slider. A magnetic head is mounted at the center air bearing surface. A center shallowly grooved surface is disposed on an inflow side of the center air bearing surface. A deeply grooved surface is disposed at a center of the bearing surface surrounded substantially by the air bearing surfaces, the side shallowly grooved surface, and the center shallowly grooved surface. The ratio of a slider length Lx to a slider width Ly satisfies the following inequality: 1.35≦Lx/Ly≦1.8, where the slider width Ly is 0.8 mm or less.

摘要： An optical delay line of a configuration in which a number of components such as a circulator and an optical coupler is reduced is to be provided. To this end, the optical delay line has a configuration in which, after an optical fiber diffraction grating having a core subjected to refractive index modulation and a cladding partly cleared of its outer circumference and an optical fiber having a cladding partly cleared of its outer circumference are brought close to each other so that the cores have mutually parallel directions of an optical axis to fabricate a directional coupler, both ends of the optical fiber are connected into an optical fiber loop. In this way, an optical delay line to generate a specific time delay for controlling optical signals can be provided in small dimensions and with a small number of components.

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.

摘要： In a floating type magnetic head support mechanism for a magnetic disk apparatus, a slider carrying a magnetic head floats a small distance above a magnetic disk in accordance with a rotation of the magnetic head to enable a reading/writing of information from/onto the disk by the magnetic head. The slider is coupled to a distal end of a load arm through a gimbal. The coupling portion is located in a common plane parallel with a floating surface of the slider, with the coupling portion including a center of gravity of the slider or being in a parallel plane closer to the floating surface than the center of gravity. The magnetic head support mechanism is so constructed that no rotational moment is applied to a slider during the access operation by the access mechanism.
