  • Patent number: 10210889
    Abstract: Implementations described and claimed herein include a method for manufacturing monolithically-integrated on-slider hybridized electronics for magnetic read/write. The method includes forming a slider body, excising a void in a surface of the slider body, monolithically integrating an electronic block into the void of the slider body, polishing the surface of the slider body, and depositing functional layers on the surface of the slider body. By integrating electronics in close proximity to transducers, operational performance and functionality may be gained.

  • Patent number: 10026424
    Abstract: A data reader may be configured with at least a detector stack positioned on an air bearing surface and consisting of a spin accumulation channel continuously extending from the air bearing surface to an injector stack. The injector stack can have at least one cladding layer contacting the spin accumulation channel. The at least one cladding layer may have a length as measured perpendicular to the ABS that filters minority spins from the detector stack.

  • Patent number: 9685178
    Abstract: A lateral spin valve reader includes a channel layer having a first end that is proximate to a bearing surface and a second end that is away from the bearing surface. The lateral spin valve reader also includes a detector structure disposed over an upper surface of a first portion of the channel layer that is proximate to the first end of the channel layer. A spin injection structure disposed below a lower surface of a second portion of the channel layer is proximate to the second end of the channel layer.
