  • Patent number: 8089722
    Abstract: A read/write head for magnetic tapes configured with an in situ radio frequency (RF) shield is provided. The RF shield of the invention inhibits device elements reading data from reading RF radiation irradiated by other device elements writing data. The RF shield may be situated between the device elements of one module and the device elements of a second module. The dimensions and materials of the RF shield may be selected depending upon the operating frequencies of the head and skin depth of materials comprising the RF shield. The data cable may be bonded to device element pads of a module using ACF bonding. AFC bonding the cable to the module may allow a metal ground plane on the cable to be extended to provide additional RF shielding.

  • Patent number: 7883607
    Abstract: A method according to one embodiment includes ion milling at a first angle of greater than about 25 degrees from normal relative to a media facing side of a thin film region of a magnetic head or component thereof for recessing the thin film region at about a constant rate for films of interest of the thin film region, planes of deposition of the films being oriented about perpendicular to the media facing side; and ion milling or plasma sputtering at a second angle of less than about 25 degrees from normal relative to the media facing side of the thin film region for recessing magnetic films therein faster than insulating films therein, the second angle being smaller than the first angle.
