    摘要： The method to detect and determine the profile of the material property or the structure changes not only on surface but also at the subsurface, of a storage medium or a scanned sample. This method comprises the following steps: (a), a nondestructive periodic or modulated perturbation is applied to the sample to be scanned. (b) the perturbed sample is then scanned using a microprobe, e.g., scanning tunneling microscopy (STM) or atomic force microscopy (AFM), which is responsive to the applied periodic or modulated perturbations and (c) the modulated output signals from the microprobe, in combination with the input perturbation signals, are processed and demodulated to automatically control the motion of the probe, and to determine the profiles of the material properties or the structure changes of the scanned sample.

    摘要： Systems and methods for forming an encapsulated device include a hermetic seal which seals an insulating environment between two substrates, one of which supports the device. The hermetic seal is formed by an alloy of two metal layers, one deposited on a first substrate and the other deposited on the second substrate. At least one of the substrates may include a raised feature formed under at least one of the metal layers. The two metals may for an alloy of a predefined stoichiometry in at least two locations on either side of the midpoint of the raised feature. This alloy may have advantageous features in terms of density, mechanical, electrical or physical properties that may improve the hermeticity of the seal, for example.

    摘要： A magnetic recording disk drive has a startup routine that frees the recording head carriers and moves them to a parking location, such as load/unload ramp or a disk landing zone, if they are stuck to the disks when the drive motor is attempted to be started. If the drive motor does not achieve its operating speed at normal startup of the disk drive, thus indicating that static friction or other "stiction" forces are adhering the carriers to the disks, a series of alternating current pulses is applied to the actuator to dither the carriers at an initial frequency that is generally equal to or above the resonant frequency of the actuator system with stuck carriers. The frequency and amplitude of the pulses is swept downward from the initial frequency and amplitude and repeated until the drive motor rotates at its operating speed. The alternating current pulses that perform the dithering of the carriers have different amplitudes or durations so that a net force is applied to the actuator to move the carriers to the parking location.
