摘要： A magnetic read/write head having a heating element to induce a desired amount of thermal protrusion in the read and write elements to control the fly height of the read and write elements over a magnetic medium. The heating element is connected with circuitry that provides an electrical bias (voltage or current) that switches polarity in order to prevent electromigration, thereby greatly increasing the life of the heating element. The polarity of the heating element can be switched upon the occurrence of a predetermined event such as between read or write events or upon activating deactivating the disk drive device or could be performed at regular, predetermined time intervals. The dual polarity bias could also be provided by applying an AC bias to the heating element.

摘要： A method for testing a magnetic head to determine whether the magnetic head is unacceptably affected by temperature variations. The test includes testing the magnetic head at different temperatures and measuring either or both of a signal amplitude and a signal asymmetry of a signal from the magnetic head at the different temperatures. If signal amplitude or signal asymmetry vary excessively as a result of the temperature change then the head can be scrapped.

摘要： A device for handling and testing individual sliders in a row-like format utilizes an elongated, row-like holder having a series of small pockets, each of which receives a single slider. After the sliders enter the holder, a clamp is moved to a closed position to retain the sliders in the holder. The holder is placed in a test fixture such that permanently mounted probes precisely engage the small pads on the sliders for multiple testing purposes. Enlarged probe pads on the test fixture are electrically interconnected with the probes to provide an operator with easy access to the slider pads. The sliders are tested in a row-like format, side by side, to reduce handling-induced electrostatic discharge and mechanical damage.
