    摘要: An electric potential is applied to first and second electrodes on opposite sides of a gap between an electronic component and a heat spreader. At least one of a thermal interface material in the gap, the electronic component and the heat spreader is subjected to a changing physical condition. The electrical capacitance between the electrodes is monitored during the changing physical condition. Such a method can be practiced using an array of components sharing a common heat spreader. An assembly for testing thermal interfaces includes a printed circuit board, a plurality of electronic components mounted to and operatively associated with the printed circuit board, a heat spreader positioned for absorbing heat generated by the electronic components, a first electrode associated with the heat spreader, a plurality of second electrodes associated, respectively, with the electronic component, and a device for monitoring electrical capacitances between the first and second electrodes. The technique may be employed for monitoring physical changes in electronic devices and other structures having interfaces between components.

    摘要: A system and method for self-servo-writing of multi-slot timing patterns is described. Individual timing marks are replaced with groups of timing mark slots. At each timing mark location, a time measurement is made by detecting a timing mark in one of the slots. Also, extensions to the existing timing marks are written in other slots. The combination of timing measurements at every timing mark and extensions to those timing marks written at every opportunity improves the overall precision of the timing propagation. The improved accuracy of timing mark placement produces a commensurate improvement in the placement of the concomitantly written servo-data. In addition, the alignment accuracy of the written pattern is less sensitive to variations in rotation speed and variations in the shape of written transitions. Moreover, only a single disk revolution is required at each servo radius to write servo data and propagate the timing marks.

    摘要: Improvements in placement of timing patterns in self-servowriting include correcting for systematic errors due to geometric effects. A correction is made for varying systematic errors, such as when the recording head has spatially separate read and write elements. Further, servopattern rotation due to residual or unmeasured systematic errors is reduced by using a once per revolution clock index derived from the motor drive current waveform or any other sensor. In one aspect of correcting for systematic errors in the writing of timing patterns on a storage medium of a storage device, a time interval between a trigger pattern written at a first radial position of the storage medium and a rotational index is measured. The rotational index is related to the rotational orientation of the storage medium with respect to a fixed frame of the storage device. The location of another trigger pattern to be written is shifted, using the measured time interval to determine the shift in location for the another trigger pattern.

    摘要: Embodiments of the present invention provide a technique to correct timing mark position error in self-servo write (SSW). In one embodiment, a method of correcting a timing mark position error of a SSW pattern of a disk drive comprises writing a plurality of timing mark bursts over a plurality of steps on a disk, the plurality of timing mark bursts including at least one misaligned burst having an intentional misalignment in a first step with respect to a corresponding burst in a neighboring second step; reading the misaligned burst and the corresponding burst at a seam between the first step and the second step to obtain a measured burst amplitude; and using the measure burst amplitude to obtain a timing mark position error, which may involve comparing the measured burst amplitude and an expected burst amplitude computed based on the intentional misalignment between the misaligned burst and the corresponding burst to obtain a timing mark position error.

    摘要: A method for writing timing marks on a rotatable storage medium, such as on a disk in a disk drive, includes the steps of: 1) during a rotation of the disk, detecting the passage of at least a portion of a first timing mark located at a first radius of the disk, and 2) writing a second timing mark at a second radius of the disk, the location of the second timing mark being based at least in part on a stored calculation of a delay from the time of passage of the first timing mark during a rotation of the rotatable storage medium. The location of the second timing mark is calculated based on alternative time intervals between detected timing marks and on various functions of the time intervals.

    摘要: During a write revolution of a storage medium, a transition is written on the storage medium while servoing on another transition previously recorded on the storage medium. During that write revolution, a position error signal corresponding to the position error of the transducer relative to the previously recorded transition is determined. That position error signal is then stored, during the write revolution, to be used in computing a reference track value associated with the transition being written to correct for the position error. Additionally, a product servo-pattern is written, which includes an embodying of the position error therein.
