  • Magnetic transducer with inner and outer magnetic medium cooperating surface zones of different convexity
    Patent number: 4097909
    Abstract: A magnetic transducer for use with a flexible disk and having inner and outer portions of respectively less and greater convex sphericity providing a central spherical surface zone within a surrounding spherical surface zone. The magnetic gap is centrally located in the central surface zone. The radius for the outer portion has a center on the center line of the transducer, and the center of curvature of the inner portion is spaced from the center line of the transducer in the direction of motion of the disk across the transducer so that most of the central zone faces the direction of disk movement.
