摘要： A magnetographic printing head (26) comprises an array of crossed elongated bar-shaped print elements (58, 62) each of which is individually magnetizable by electrical conductors (40) wound about respective ones of the print elements (58, 62). The print elements (58, 62) are arranged in two parallel arrays which are spaced apart from each other to define a passage (24) through which a magnetic medium (22) is to be passed for the imprinting of marks (66) thereon. A mark (66) can be imprinted at each cross point (64) of the crossed arrays upon application of sufficient magnetizing current to each of the print elements (58, 62) at the cross point (64). The print elements (58, 62) are specifically shaped to provide for concentration of magnetic fields at the cross points (64) in two dimensions to accomplish high resolution printing. The concentration of the fields is accomplished in one embodiment of the invention by the use of a knife-edge (68) configuration to opposed facing surfaces of the elements of the opposed arrays, and in a second embodiment by a set of pedestals (72) upstanding from the elements of one of the arrays. The resulting configuration of the print head (26) has structural simplicity which permits economical fabrication while retaining high resolution in the printing.

摘要： Method for controlling plating in an electroless plating process. The plating rate is continuously monitored. The plating rate is compared with a set point plating rate. A control voltage is derived proportional to the difference in .plating rate and the desired plating rate, the integral of the difference, and the derivative of the difference. The control voltage is applied to a replenishment control for controlling the replenishment rate of a constituent chemical of the plating process.

摘要： A method for writing patterns on a medium, especially self servowriting a rotating disk in a disk drive including a servo controlled actuator for positioning the head radially with respect to the disk, in which a position error signal equals a difference between a reference waveform and a measured relative position waveform derived from readback signals from the head interacting with the disk, including writing servo patterns on successive radial tracks of the disk using the actuator and deriving the reference waveform as a function of closed loop transfer function of the actuator and at least one measured position waveform. The frequency dependent gain of the servo loop may be set so that closed loop response of the servo loop has a magnitude less than unity at every integer multiple of disk rotation frequency, yet is high enough to provide substantial reduction of mechanical disturbances. Writing a series of first patterns along a track, displacing the head a known fraction of a track to a displaced position, and reading from selected ones of the first patterns position information for determining deviation information representative of deviation of the head from the known fraction, and using the deviation information to propagate second patterns at the displaced position with the deviation information encoded in the patterns. Spacing between adjacent tracks can be adjusted without writing the entire disk. Deviations in demodulated position signal arising from random placement errors in servo patterns may be cancelled. Apparatus for performing the methods and disk drives written by the method.

摘要： A device and method for capacitive measurement and control of the fly height of a recording slider. A recording slider 12 is vertically spaced from a rotating disk surface 14 by an "air bearing". The disk 10 has a first electrically conductive pattern 16, 22a-c, 72 at its surface. The first pattern has an edge 18, 74 with a length extending, for example, radially. The recording slider has one or more electrically conductive rails 30, 30A extending transverse to the radial pattern on the rotating disk. As the disk rotates, the edge of the pattern on the disk scans across the rail of the slider. By measuring the electrical capacitance between the slider and the pattern on the disk, and by processing the electrical capacitance measurement signal, a vertical spacing signal proportional to the vertical spacing between the disk and the slider can be obtained. Compared to prior methods and devices, more detailed, more precise and more accurate vertical spacing information can be obtained.

摘要： A method and structure permit the precision alignment in the packaging of optical components (10), such as lasers, detectors, lenses and waveguides. The technique involves capacitance measurements of an array of plates placed on the optoelectronic device chip and its package substrate (12). The technique uses phase sensitive detection to sense the total current capacitively coupled into a passive plate (14) on the device chip (10) from two overlapping plates (16, 18) located on the package substrate. When the device chip (10) is properly aligned with respect to the package substrate (12), the summed current sensed with a third overlapping plate (22) on the package substrate is a null.
