摘要： In a method of pre-contact detection and active damping of air bearing vibrations in a hard disk drive, a slider is isolated from ground. The slider is then capacitively coupled with a hard disk of the hard disk drive via a thermal fly-height control (TFC) heating element. An alternating current (AC) signal is applied to the slider via the TFC heating element to control the amplitude of the slider.

摘要： A disk pack, comprising at least one hard disk, is rotatably mounted to a housing. The disk pack defines an axis of rotation and a radial direction relative to the axis. At least one actuator mounted to the housing is coupled with a suspension and is movable relative to the disk pack. A slider, comprising a slider body and a head configured to read data from and write data to at least one hard disk, is coupled with the suspension. A first suspension electrical interconnect is configured to electrically couple a first signal conducting pathway with the slider and with a first non-terminated signal pathway. A second suspension electrical interconnect is configured to electrically couple a second signal conducting pathway with the slider and with a second non-terminated signal pathway. The length of the second non-terminated signal pathway is selected to achieve a desired impedance level.

摘要： In a method of biasing a slider, a bias voltage is generated for biasing a slider. The bias voltage is integratedly coupled to a conductive body of the slider via an existing signal path of the slider such that the slider is biased with the bias voltage. The existing signal path is primarily used for conveying another signal to or from the slider but at least sometimes conveys the bias voltage to the conductive body in an integral fashion along with another signal.

摘要： Impedance compensation features are used along the transmission-line path between a transmitter/driver/source and the receiver/transducer to compensate for the impedance discontinuities or mismatches (for example, those caused by physical interconnection features) and/or to improve the frequency response of the signal transfer along the transmission line. The impedance compensation features are non-uniformities with impedance characteristics selected to compensate for the target impedance discontinuities. The compensation features can be non-uniformities (geometric structures designed to have specific impedance characteristics) in the electrically conductive traces that are integrated in the interconnect transmission line between the transmitter/driver/source and the receiver/transducer. The effective impedance level of the transmission line can be lowered or raised using the compensation features.
摘要翻译：阻抗补偿特征沿着发射机/驱动器/源与接收器/换能器之间的传输线路径被使用以补偿阻抗不连续性或不匹配（例如，由物理互连特征引起的）和/或改善频率响应沿着传输线的信号传输。阻抗补偿特征是非均匀性，其阻抗特性被选择以补偿目标阻抗不连续性。补偿特征可以是集成在发射器/驱动器/源极和接收器/换能器之间的互连传输线中的导电迹线中的非均匀性（被设计为具有特定阻抗特性的几何结构）。可以使用补偿特性降低或提高传输线的有效阻抗水平。

摘要： A signaling apparatus and method are described that use reflected signals to increase the total current delivered to a receiver. Dynamic source-side transmission line termination control is employed to generate reflected signals that constructively add to a nonreflected signal to enhance the signal at the receiver. Switching controls selectively connect and disconnect the transmission line source-side termination resistors to either provide signal termination or remove it. Driver designs using either voltage or current sources for use in signaling systems (including, for example, magnetic storage devices with inductive coil based write heads) are described.
