摘要： An apparatus and methods for measuring and compensating for birefringence in a rotating ground glass disk (20) such as are employed in polarization based optical flying height testers. The polarized light (1, 3) impinges on the top surface (24) of the disk (20) and is refracted through the disk to a measurement point (90) on the opposite surface (25) from which it is reflected back through the disk (20) and refracted before it exits the disk (20) in a beam (9) containing both s .alpha.and p polarizations which are detected by a phase detector (13) which measures any difference in phase between the s and p polarizations. Any variation of the phase .theta..sub.G with respect to the position defined by the measurement point provides the birefringence parameters b.sub..parallel.,b.sub..perp. for the positions on the disk (20). The phase detector (13) measures the phase .theta..sub.G at a skew angle .zeta. defined between the plane of incidence (101), defined by the existing beam (9) and the incident beam (3), drawn through the measurement point (90) perpendicular to a radius line (102) for the disk (20).

摘要： A test apparatus for testing a plurality of magnetic recording heads. The apparatus includes a tool which supports a bar that contains a number of individual magnetic recording heads. Alternatively, the tester may contain a tool which supports a plurality of individual sliders. The tool locates the heads within a magnetic field emanating from a coil wound magnet. The magnet has a length and permeability that provides a uniform magnetic field for each slider in the entire bar. The test apparatus includes a probe card that has a plurality of probe needles which make simultaneous contact with the bonding pads of each head. The needles are coupled to a test circuit that applies a constant current to the magnetic recording heads and measure a change in voltage as a function of a varying magnetic field. The tester can sequentially test the heads without spatially moving the bar, thereby minimizing the test cycle time of testing the heads. Alternatively, the tester may test two or more of the heads simultaneously.

摘要： A coupling device for ensuring a precise alignment between a disk-drive suspension and a static-attitude testing tool along a predetermined axis. The device consists of the combination of a support post or ridge etched in relief precisely along the longitudinal axis of a disk-drive suspension, or a spherical-radius post protruding through an etched relief, and a compressive mechanism in a static-attitude testing tool adapted to provide a compressive force in a direction coincident with the main axis of the support post in the suspension. A conventional tooling hole is provided at a predetermined location on the suspension, typically along its longitudinal axis, to enable alignment between the testing tool and the suspension. As the tool's compressive mechanism begins pushing against the support post to impart a load, the point of contact between the two is determined by the fixed axial position of the support post and remains fixed even if the testing tool and the suspension are lightly misaligned, thereby causing the force exerted by the compressive mechanism to be transferred to the suspension in perfect alignment with its longitudinal axis, as intended.

摘要： A calibration medium that is used to calibrate a flying height tester which measures the gap of an air bearing formed between a magnetic recording head and a substrate. The medium contains a first ridge and a second ridge that extend from an underlying substrate. The ridges may be coated with a reflective material. A flying height tester can be calibrated by measuring light reflected from each ridge. The ridges have varying thicknesses so that the calibration medium will produce multiple data points.

摘要： An apparatus for testing magnetic heads that interact with magnetic disks includes a translational slide and a rotatable arm mounted to one end of the slide. The translational slide moves the rotatable arm in a longitudinal direction parallel to the surface of a magnetic disk. The arm rotates the magnetic head to different positions relative to data tracks on the disk. A second translational slide moves the magnetic head vertically above the disk to adjust the vertical position of the head. The three movements of the head, (1)horizontally across the disk, (2)rotationally by the arm, and (3)vertically relative to the disk surface are controlled by servomechanisms. A read/write amplifier circuit is connected to the head under test. The test apparatus is controlled by a computer that interfaces with circuitry connected to the servomechanisms.

摘要： A system and method for determining the velocity and/or position of a coil driven actuator arm without the aid of servo signals. A sample-hold unit is used to measure no-motion coil voltage in the voice motor coil while applying a predetermined coil current. Then, while the same magnitude (opposite direction) current is applied to move the actuator arm, the coil voltage is measured. The coil voltage is reduced by the measured no-motion coil voltage, producing a measurement of back-emf. The back-emf may be amplified by a predetermined factor to yield an estimation of velocity, and this amount may be integrated to provide a gauge of relative actuator arm position.

摘要： An audio-book player includes a member capable of indicating to a blind person that a recording medium is loaded in or unloaded from the body proper. The audio-book player, which reproduces written data recorded on a recording medium as voice, includes a body proper into which the recording medium can be unloadably loaded and a member for identifying a loading state, in which the recording medium is loaded in the body proper, and an unloading state, in which the recording medium is unloaded therefrom. With this structure, the identifying member identifies the states by changing its tactile impression, so that blind persons can understand the states wherein recording medium is loaded in or unloaded from the body proper.
