    Abstract: A network management system includes a domain administrating server (DAS) that stores a virtual catalog representing an overview of all files distributively stored across a network domain currently or in the past. The current and historical file information is used for assisting in auditing or locating files located anywhere in the domain. The current file information is used for assisting in transferring files across the domain. The domain administrating server (DAS) also includes a rule-base driven artificial administrator for monitoring and reacting to domain-wide alert reports and for detecting problematic trends in domain-wide performance based on information collected from the network domain.

    Abstract: A device for measuring flying heights of a read/write head (30) in a disk drive down to zero microinches using interferometry, wherein the flying height of the head above the disk surface is calculated by directing white light to the under side of a rotating disk (20). A thin metallic layer (22) on the disk acts as a beam splitter, reflecting a first portion of the beam back downward, and allowing a second portion of the beam to pass therethrough to be reflected back downward off of the bottom surface of the read/write head. Once reflected, the two portions will combine to form an interference pattern. This pattern is then input to a spectrometer, which creates an intensity profile to represent the unique height of the air-bearing slider (36) above the beamsplitter layer. The flying height is finally determined by subtracting from this height the thickness of the spacer layer (24).

    Abstract: A method and apparatus for performing error detection on data transfer through a parallel interface port (18) at a substantially increased data transfer rate with a minimum of handshaking. Blocks of data are transferred between a sending device (12) and a receiving device (14 and/or 16), and each of the respective devices maintain a checksum (50, 52a, 52b). Each checksum comprises an initial value, and added to that value is the value of each data byte transferred through the parallel port interface. After a block of data bytes has been transferred, the checksum maintained by the sending device and the receiving device are compared. If the checksums are equal, no error is assumed to have occurred during the data transfer. If the checksums are not equal, an error is assumed to have occurred during the data transfer, and the data is retransferred with the previously transferred block discarded.

    Abstract: A quadrature based embedded servo control system is provided to realize a high track density, high-performance hard disk drive system (10). Each data sector includes a gray code field spanning the entire width of the data track and a quad-servo burst pattern having first, second, third, and fourth servo burst fields distributed along the length of a portion of the data sector. The center point of the first, second, third, and fourth servo bursts are sequentially offset from the adjacent burst by a radial distance equivalent to one-half of the data track width. The quad-servo burst pattern is used with a track-following algorithm based on the quadrature value of (A + B) - (C + D) to obtain a substantially increased servo lock range. A second gray code field extending substantially the width of the data track and second quad-servo burst pattern substantially identical to the first is provided near a mid-point in the data portion of the data sector to increase the servoing information sample rate and accuracy, thereby permitting substantially increased data track densities to be utilized.

    Abstract: A read channel is described for use in a storage device including a storage medium (22a-d) for storing data, an interactive element (24a-h) for reading information from and writing information on the storage medium (22a-d) and a processor (35) for performing control functions in the storage device. The read channel comprises a set of electronic components (50, 52, 54) for receiving and processing information read by the interactive element from the storage medium. An adjustable noise generator (56) is included in the read channel and is coupled to the set of electronic components. The noise generator (56) is selectively operated to introduce noise into the set of electronic components to cause the set of electronic components to operate at a marginal level of performance and thereby increase the error rate of the read channel. A calibration of the read channel is performed when the read channel is operating at the marginal level of performance to decrease the time required to accumulate error statistics used in the calibration.
