A read sensor stack is deposited on the substrate. A mask is provided on the on the read sensor stack. The mask has a pattern that covers a first portion of the read sensor stack corresponding to the read sensor, covers a second portion of the read sensor stack distal from the read sensor, and exposes a third portion of the read sensor stack between the first and second portions. The read sensor is defined from the read sensor stack. A hard bias layer is deposited. An aperture free mask layer including multiple thicknesses is provided. A focused ion beam scan (FIBS) polishing step is performed on the mask and hard bias layers to remove a portion of the mask and hard bias layers based on the thicknesses."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and system for providing a magnetic recording transducer using an ion beam scan polishing planarization","description":"A method and system for fabricating a read sensor on a substrate for a read transducer is described.
