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： PROBLEM TO BE SOLVED: To improve the quality of semiconductor workpiece surfaces. SOLUTION: A blade 10 is built of different materials suitable for dealing with different materials of the workpiece, and has a three-layer structure with a wire-dealing layer 10b at the middle sandwiched in between resin-dealing layers 10a on both sides. In a substrate 7 mounted with a multiplicity of elements, a base material 2h is provided for instance made of a glass-containing epoxy resin, an en-bloc molding 8 is formed thereon, and also power-feeding wires 2d to be copper-plated are provided on the dicing line. During the dicing process after the en-bloc molding process, the resin section of the substrate 7, the molding 8, and the wires 2d may be diced by one and the same blade 10 because the blade 10 is built of materials for properly dealing with the different materials of the workpiece, and this improves semiconductor device quality.

摘要： PROBLEM TO BE SOLVED: To prevent damages of a magnetic head and a magnetic disk by removing dust adhered from a recording/reproduction area on the surface of the magnetic disk to an outer area in a magnetic disk device. SOLUTION: Suspension to support the magnetic head is provided with the magnetic head to perform a normal recording/reproducing operation and a cleaning head for the purpose of removal of the dust and the magnetic head temporarily stops in time at least over one rotation in the vicinity of inner and outer peripherals of the recording/reproduction area on the magnetic disk or performs a seek operation before the magnetic head to complete the normal recording/reproducing operation is retreated on a magnetic head holding member from the surface of the magnetic disk. In this case, the cleaning head is placed in an area outer than the recording/reproduction area on the magnetic disk and thoroughly removes the dust adhered on the magnetic disk surface.
