    摘要: A method for providing a structure in a magnetic transducer is described. The method includes performing a first planarization that exposes a top surface of the magnetic transducer. This first planarization also terminates before a portion of a first planarization buffer layer is removed. The method also includes providing a second planarization buffer layer after the first planarization is performed. The second planarization buffer layer is above the first planarization buffer layer. The method also includes performing a second planarization. This second planarization does not completely remove the second planarization buffer layer. The method also includes performing a third planarization terminating after the first planarization buffer layer is exposed and before the first planarization buffer layer is completely removed.

The method and system include providing at least one side gap layer that covers the side(s) and the top of the pole. At least one sacrificial layer is provided on the side gap layer(s). The sacrificial layer(s) are wet etchable and cover the side gap layer(s). The magnetic recording transducer is planarized after the sacrificial layer(s) are provided. Thus, a portion of the side gap and sacrificial layer(s) is removed. A remaining portion of the sacrificial layer(s) is thus left. The method and system also include wet etching the sacrificial layer(s) to remove the remaining portion of the sacrificial layer(s). A wrap around shield is provided after the remaining portion of the sacrificial layer(s) is removed.

    摘要: Fall detection method and systems with its unique designed sensors are disclosed. The capacitive sensing based systems use the abrupt changes of the capacitance value to detect whether a real fall event happens, while the reed sensor/or reed switch based systems work in power saving passive mode to detect the real fall event by analyzing the binary “on/off” signal available from the reed sensor/or reed switch. Both rely on the orientation change of the host body respects to local gravity direction during the falling process. The system can present either as a standalone system or a built-in component with supporting software installed on other devices.
