    摘要: A novel method for defining a touch-down power for a head that has a head-based flying height actuator is disclosed and claimed. A linear relationship between power and spacing is derived by fitting to first and second transducer-disk spacings corresponding to first and second electrical powers applied to the head-based flying height actuator. A third spacing between the transducer and the disk is determined when a greater third electrical power is applied to the flying height actuator. An estimated third spacing between the transducer and the disk, corresponding to application of the third electrical power to the flying height actuator, is calculated using the derived linear relationship and the third electrical power. The touch-down power is defined to be substantially equal to the second electrical power if an error between the third spacing and the estimated third spacing is larger than a first threshold.

    摘要: A method to detect helium leakage from a disk drive enclosure is disclosed and claimed. A measurement electrical current is passed through a temperature sensor disposed within the disk drive enclosure. A reference electrical resistance corresponds to a reference temperature of the temperature sensor. A heating electrical current is passed through the temperature sensor. A heated electrical resistance of the temperature sensor, corresponding to a heated temperature of the temperature sensor that exceeds the reference temperature by at least 5° C., is determined. A value that corresponds to a quantity of helium within the disk drive enclosure is determined based on the reference electrical resistance and heated electrical resistance.

    摘要: An interference-canceling receiver is configured for cancelling inter-symbol interference due to both inter- and intra-channel interference in coded, multiple-access, spread spectrum transmissions that propagate through frequency-selective communication channels. The receiver mitigates the effects of post-cursor inter-symbol interference using feedback of previously estimated symbols, and mitigates pre-cursor inter-symbol interference using an interference canceller, such as an iterative interference canceller.

    摘要: A read/write head for use in a data storage device to control the low dynamic flying height in order to achieve high data recording storage capacity of magnetic hard drives. The read/write head is designed for use in a data storage device that includes a storage medium having a recording surface. The head comprises a pole tip region and an actuator. In turn, the actuator includes an excitation source for generating a magnetic field, and a magnetostrictive plate for expanding in response to the magnetic field, resulting in a protrusion in a section of the pole tip region along a direction towards the recording surface, so that the head flies above the recording surface at a flying height lower than a nominal flying height.

    摘要: A method for finding an error in a computer program is disclosed. A sequence of machine instructions performed by a processor is recorded as trace data. A mapping file is accessed. A source code instruction is translated into a machine code instruction according to a mapping found in the mapping file. Further, at least a portion of the trace data is searched through until the machine code instruction is found. In addition, a first execution time of the machine code instruction is determined by reviewing the trace data in a first vicinity that an address of the machine code instruction is located. Further, a second execution time of the next machine code instruction is determined by reviewing the trace data in a second vicinity that an address of the next machine code instruction is located. Accordingly, performance data is calculated by subtracting the first execution time from the second execution time. The performance data is displayed.

    摘要: Methods are provided for fabricating an electrical lapping guide, and for using the electrical lapping guide to fabricate a transducer of a magnetic recording head. Additionally, transducers comprising an electrical lapping guide are also provided. Methods of fabricating the electrical lapping guide comprise forming a resistive element proximate to a shield pedestal. Accordingly, the resistive element is both aligned with the shield pedestal in a transverse direction, and closely spaced from the shield pedestal in a longitudinal direction. The resistance of the resistive element correlates well with a throat height of the shield pedestal, and the correlation is utilized in the methods of fabricating the transducer. When a magnetoresistive stripe is uses as a second electrical lapping guide while fabricating the transducer, the two can be used to control a tilt angle in the transverse direction during lapping.
