    摘要: Metal alloy heatsink films for magnetic recording media are disclosed. The metal alloy heatsink films possess both high thermal conductivity and improved mechanical properties such as relatively high hardness. The metal alloy heatsink films also have controlled microstructures which are compatible with subsequently deposited crystalline magnetic recording layers. The films may comprise single phase CuZr or AgPd alloys having a selected crystal structure and orientation. The combination of high thermal conductivity, good mechanical properties and controlled microstructures makes the metal alloy heatsink films suitable for various applications including heat assisted magnetic recording systems.

    摘要: A data storage medium for perpendicular recording has a substrate and a ferromagnetic layer on the substrate for storing data bits. The ferromagnetic layer has a plurality of elongate grains of magnetizable material extending perpendicular to the substrate which form magnetic domains representative of data. Each magnetic domain is separated from adjacent magnetic domains by a bit edge domain wall region. Each elongate grain has a perpendicular height that is greater than a width of the bit edge domain wall region.

    摘要: The invention includes improving or enhancing exchange coupling within a thin film layer. The improvement or enhancement to the exchange coupling occurs between the grains that are deposited to form the thin film. The improvement or enhancement to the exchange coupling between the grains of the thin film results from annealing the thin film at an elevated temperature for a period of time. A thin film structure and/or a magnetic recording layer made in accordance with the invention are disclosed.

    摘要: The system is a closed-loop feedback mechanism that helps a user correct improper posture. The system consists of two or more system enclosures on opposite ends of a loop formed by connecting the enclosures with a necklace portion and multi-conductor cable of essentially equal length. Worn around the neck, one system enclosure is centered on the upper chest and the other enclosure is centered on the upper back. The two enclosures measure the angle of head back and neck to upper body and detect when a user is slouching. When so detected for some predetermined period of time, a transducer in one enclosure vibrates silently to alert the user that he or she is slouching. The vibratory alert ends when a user corrects his or her posture.

    摘要: A system and method for controlling an AC motor drive includes a control system programmed with an algorithm configured to optimize operation of the motor drive. Specifically, the control system is programmed to input an initial voltage-frequency command to the drive. The initial voltage-frequency command includes a voltage reference and a frequency reference corresponding to an operating point of an initial voltage/frequency (V/Hz) curve. The control system monitors a real-time output of the drive, modifies the voltage reference based on the real-time output of the drive, and transmits a modified voltage-frequency command to the drive. The modified voltage-frequency command corresponds to an operating point of a modified V/Hz curve defined by the modified voltage reference and the initial V/Hz curve.
