摘要： In accordance with various embodiments, a rotatable member is mounted to a spindle hub so that initial servo data previously provided to the rotatable member are eccentrically offset with respect to a rotational center of the spindle hub. Compensation vales are determined to characterize said offset, after which final servo data are provided to the rotatable member in relation to the initial servo data and the determined compensation values. The final servo data are nominally concentric with the rotational center of the spindle hub.

摘要： Methods for writing servo fields on a rotatable data storage disk using reference patterns on the data storage disk include generating a clock signal, reading a reference pattern signal from a surface of the disk, generating a phase error signal in response to a phase offset between the clock signal and the reference pattern signal, subtracting a timing control value from the phase error to provide an adjusted phase error, generating a frequency control signal in response to the adjusted phase error, and adjusting the frequency of the clock signal. The timing control value is generated in response to the phase error signal and the frequency control signal.

摘要： The present invention is a secure Web platform (SWP) implementing a mandatory access control policy to enable a plurality of remote users operating Web browsers Internet access to CGI applications in response to HyperText Transfer Protocol (HTTP) requests. The SWP employs a computer having a compartmentalized process and file structure separated in accordance with a mandatory access control policy into an outside compartment comprising a Web server having a root directory chrooted to a directory tree containing only the minimal set of files required to interface the SWP with the Internet, and an inside compartment comprising a plurality of CGI applications having root directories chrooted to a directory separate from the Web server such that the Web server cannot communicate directly with the CGI applications, and a trusted gateway agent for communicating between the Web server and the CGI applications.
