摘要： Techniques are disclosed for identifying the locations of equipment in computing environments such as data centers. For example, a method of identifying a plurality of computing devices in a computing environment includes the following steps. A first temperature-indicative map of the plurality of computing devices is generated while the plurality of computing device is in a first mode. The first temperature-indicative map is overlaid with a facility map associated with the computing environment. A first one of the plurality of computing devices is placed into a second mode. The second temperature-indicative map of the plurality of computing devices is generated while the first one of the plurality of computing devices is in the second mode and the remainder of the plurality of computing devices is in the first mode. The second temperature-indicative map is overlaid with the facility map associated with the computing environment. The first temperature-indicative map is compared with the second temperature-indicative map to determine a location of the first one of the plurality of computing devices.

摘要： A method and apparatus are provided for implementing improved phase alignment in a direct access storage device (DASD). A reference clock input is received for providing a system clock. Locking to a synchronization field of a readback signal is performed by adjusting the phase of the system clock. A timing mark is detected and then the adjusted phase of the system clock is held. Responsive to the detected timing mark, a reference delay of a predefined number and fraction of system clock periods is identified. At an end of the reference delay, a write circuit accepts data and generates write signals for a write operation. The phase of the system clock is adjusted corresponding to a predefined fractional delay and is used to run a programmable counter that counts the predefined number of system clock periods corresponding to the reference delay.

摘要： Off-track time shift estimates are determined and used in order to write subsequent trigger patterns on a storage medium at different track pitches. Various procedures for determining an off-track time shift estimate are provided. These procedures include measuring time intervals between a related set of trigger patterns and another trigger written on the storage medium; measuring time intervals between a motor index and a particular trigger pattern at two different radial locations; measuring the difference in the center location of two trigger patterns written at different radial locations; and microjogging a recording transducer during the interval between two different trigger patterns.

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： Apparatus and methods for improved thermal proximity imaging are provided. A data storage medium surface is moved relative to a sensor, in one embodiment a magnetoresistive read/write element. Topographical variations on the storage medium induce temperature changes in the sensor. These temperature changes are monitored to detect the location and nature (e.g., height) of the topographical variations on the medium surface. A feedback circuit using an impedance bridge is disclosed for sensing instantaneous changes in the temperature of the sensor, correcting for the changes and, therefore, keeping the temperature of the sensor substantially constant. By keeping the temperature of the sensor constant, the topographical variations can be detected without any adverse impacts of the surrounding thermal environment on the detection response time.

摘要： A mechanism for servowriting on a storage medium of a storage device. The storage device has a transducer and a servo loop for positioning the transducer with respect to the storage medium. At least one transition is written on a track of the storage medium, while servoing on other transitions previously recorded on the storage medium. A reference waveform is derived as a function of a closed loop response of the servo loop and a position error waveform. The position error waveform corresponds to one or more position errors of the transducer relative to the previously recorded transitions. The reference waveform is usable in writing subsequent tracks on the storage medium. Using the reference waveform for writing subsequent tracks provides a substantial rejection of mechanical disturbances by the servo loop.

摘要： Improvements in placement of timing patterns in self-servowriting include correcting for random errors. Random errors may be caused by variations in disk velocity and therefore, one technique for correcting for random errors includes reducing velocity jitter. Additionally, random errors can be corrected by improving interval control during the propagation of trigger patterns used in writing timing information on storage media. Further, random errors, in the writing of timing information, can be corrected during a single revolution of the storage media. This eliminates additional rotations, thereby providing a large capital cost savings.
