  • Publication number: 20160351213
    Abstract: A method of making a magnetic head is provided. The method includes forming a first read sensor and a first electrical contact formed with a first shunt region. The method further includes forming a first mid-shield layer on the first read sensor, the first mid-shield layer being electrically connected to the first electrical contact. Additionally the method also includes forming a second mid-shield layer over the first mid-shield layer. Further, the method also includes forming a second read sensor over the second mid-shield layer, the second read sensor having a second electrical contact formed with a second shunt region electrically connected to the first shunt region.

  • Patent number: 6181673
    Abstract: A slider is used in an optical or magneto-optical head having an optical assembly mounted on the slider body, for directing a read-write laser beam onto and from a data storage disk. The optical assembly includes an optical fiber a mirror a quarter wavelength plate, and a lens. The optical fiber guides the laser beam along an optical path defined by the optical assembly and the slider body. The laser beam emanating from the optical fiber impinges upon the mirror and is reflected thereby onto and through the quarter wavelength plate. The laser beam continues its travel along the optical path through the lens and a magnetic coil assembly onto the disk. The slider includes a channel pattern formed on its upper surface for positioning the optical components on the slider body. The channel pattern includes a plurality of channels that define an optical path, and a plurality of cavities formed along these channels for receiving various components such as optical, magnetic and electrical components.

  • Patent number: 6097575
    Abstract: An optical or magneto-optical (MO) head comprises a head formed of two main parts: a housing and a body. The housing supports optical and magnetic components to be secured to the slider, and the body provides an air bearing surface and further supports the housing. The housing includes a pattern of channels and grooves that retain the optical and magnetic components, and that can be produced with extreme accuracy, so that the cumulative tolerance of the head varies within a very tight range. The components are interlocked within, or secured to the slider in a self-aligned disposition, and do not become detached, even under extremely harsh operating conditions. In addition, the self-alignment feature significantly reduces, if not entirely eliminates the need to align certain components after they have been mounted onto the slider. The slider design enables the head to be mass produced and assembled.
