Abstract:
A head assembly for interfacing with a storage medium on a disk, comprising:a first slider having a leading edge, a trailing edge, a first side, and a second side, said first slider comprising: (i) a first rail, extending longitudinally along said first side of said first slider, and having a bleed leading edge step formed proximate said leading edge of said first rail for reducing an air bearing under said first rail; (ii) a second rail, extending longitudinally along said second side of said first slider, and having a structured leading edge step formed proximate said leading edge of said second rail for improving an air bearing under said second rail; (iii) a sensor disposed proximate a trailing edge of said first rail of said first slider for communicating with said storage medium; and a second slider aligned with said first slider and having a leading edge, a trailing edge, a first side, and a second side, said second slider comprising: (i) a first rail, extending longitudinally along said first side of said second slider and having a bleed leading edge step formed proximate said leading edge of said first rail for reducing an air bearing under said first rail, said first rail of said second slider being aligned with said second rail of said first slider; (ii) a second rail, extending longitudinally along said second side of said second slider, said second rail of said second slider being aligned with said first rail of said first slider, and having a structured leading edge step formed proximate said leading edge of said second rail for improving an air bearing under said second rail; (iii) a sensor disposed proximate a trailing edge of said first rail of said second slider for communicating with said storage medium; and wherein said bleed leading edge step and said structured leading edge step of said first and said second sliders provide a tuned leading edge step scheme for an improved head performance by forcing said storage medium to comply in an advantageous way to cause intimacy at said sensor.
