摘要： A method and apparatus for managing data, particularly in regard to non-volatile memory cells. In some embodiments, at least two actuating conductors are at least partially surrounded by a main ferromagnetic core and an adjacent hard magnet. When current is conducted through the actuating conductors, a flexible beam is induced to traverse a first air gap that defines a high resistance position and a low resistance position.

摘要： The presently disclosed technology teaches integrating disc drive electronics into a transducer head. Decreased electrical transit times and data processing times can be achieved by placing the electronics on or within the transducer head because electrical connections may be made physically shorter than in conventional systems. The electronics may include one or more of a control system circuit, a write driver, and/or a data buffer. The control system circuit generates a modified clock signal that has a fixed relation to phase and frequency of a bit-detected reference signal that corresponds to positions of patterned bits on the disc. The write driver writes outgoing data bits received from an external connection to off-head electronics directly to the writer synchronized with the modified clock signal. The data buffer stores and converts digital data bits sent from the off-head electronics to an analog signal that is synchronized with the modified clock signal.

摘要： A magnetic writer includes a write element having a write element tip and a conductive structure adjacent the write element. The conductive structure includes two conductive elements positioned substantially parallel to one another and separated by an electrically insulating material. Each of the conductive elements carries a time-varying signal to generate an oscillating magnetic field from a displacement current between the two conductive elements, with the oscillating magnetic field being proximate the write element tip and extending parallel to the air bearing surface. A frequency of the oscillating magnetic field is a function of a frequency of the time-varying signal.

摘要翻译： 目前公开的技术教导将盘驱动器电子器件集成到换能器头中。 电子传输时间和数据处理时间可以通过将电子设备放置在传感器头上或内部来实现，因为电气连接可以在物理上比传统系统中更短。 电子设备可以包括控制系统电路，写入驱动器和/或数据缓冲器中的一个或多个。 控制系统电路产生修正的时钟信号，该修改的时钟信号与对应于盘上的图案位的位置的位检测参考信号的相位和频率具有固定的关系。 写入驱动器将从外部连接接收到的外部数据位写入到与修改的时钟信号同步的写入器件到写入器。 数据缓冲器存储和转换从头部外部电子装置发送的数字数据位到与修改的时钟信号同步的模拟信号。
