摘要： A method and apparatus for processing a magnetic transducer which uses gallium ion beam milling to precisely define pole tip widths of the magnetic transducer. The gallium ion beam may be defocused to improve definition of the region which is damaged by gallium ion implantation. The precision pole tip widths provide a transducer that may record correspondingly precise track widths on a magnetic storage medium, such as a rotating disk. Subsequent to the ion milling process, the invention restores the magnetically conductive properties of the pole tip region, which may be degraded as a result of the ion milling process, by means of a lapping process.

摘要： A system includes a host device and a disk drive interfaced with the host device are described as well as an associated method. The disk drive includes a magnetic media for storing information using an actuator arrangement to perform a data access by moving at least one head proximate to the magnetic media. The information may be subject to corruption when the disk drive is exposed, during the data access, to a given stray magnetic field having a given minimum magnetic field intensity. The given stray magnetic field will not corrupt the information on the magnetic media with the actuator arrangement positioned away from the magnetic media. A stray magnetic field protection arrangement is configured for detecting an ambient magnetic environment for use in causing the actuator arrangement to park responsive to the detection of at least the given minimum magnetic field intensity.

摘要： The disclosed MMW wave sensing camera calibration arrangement that generally includes a millimeter wave camera that uses an energy emission calibration panel as a calibration standard. The MMW camera is positioned opposite the calibration panel in the MMW camera's field-of-view. The calibration panel is held at a constant temperature to provide a standard emission of millimeter waves that is sensed by an MMW sensor to set or otherwise calibrate the MMW camera to a baseline emissivity value corresponding to the panel. The MMW camera is linked to a microprocessor and non-transient computer memory containing a calibration routine that is configured to reset the baseline only when nothing obstructs the calibration panel's field-of-view. A visual display is linked to the MMW camera and configured to display an MMW signature of a metal object that is disposed on a person's body when the person's body is in the field-of-view, the metal object concealed by clothing worn over the person's body.

摘要： A tape drive apparatus for reading and writing data on a magnetic tape includes at least one transducer that interacts with the magnetic tape. A temperature control element is positioned to thermally expand the transducer. A control system controls the amount of current supplied to the temperature control element. A sensing circuit senses the distance between the transducer and the data storage tape. The system generates a spacing signal indicative of the sensed distance and is stored as spacing data. A temperature control element is controlled based upon spacing data to adjust the spacing between the transducer and the tape. The temperature control element may be controlled based upon a fixed adjustment or empirical data. A method is disclosed for controlling spacing between the transducer and a magnetic storage tape by heating the transducer head to cause thermal expansion and reduce pole tip recession.

摘要： A magnetoresistive read/recording head for use in a fixed disk drive data storage device is formed by the steps of first, photolithographically depositing the head on one surface of a slider block, second, applying, a conductive film preferably of carbon or a silicon/carbon multi-layer film over the head and onto the block surface, and then milling the write tip portion of the head with a focused ion beam. The remaining conductive film is then removed in an oxygen plasma which chemically removes the remaining conductive film. The conductive layer is transparent to the focused ion beam and conducts electrostatic charge away from the head during the milling operation thus preventing electrostatic discharges from occurring which otherwise would damage the head.
