Abstract
A transducing head for use with a storage medium rotatable about an axis includes first and second writers for writing to the storage medium. The first writer is configured for dedicated writing to a first radial region of the storage medium, and the second writer is configured for dedicated writing to a second radial region of the storage medium. The second radial region is located radially outward from the first radial region.
Claims22
A transducing head for use with a storage medium, the transducing head comprising:
- a first writer configured for dedicated writing to a first radial region of a surface of the storage medium;
- a second writer configured for dedicated writing to a second radial region of the surface of the storage medium, the second radial region located radially outward from the first radial region;
- and
- a shield shaped with a substantially trapezoidal perimeter and positioned between the first and second writers for magnetically decoupling the first and second writers.
A transducing head for use with an adjacent magnetic storage medium, the transducing head comprising:
- a first writer having a pole tip with a trapezoidal perimeter along an air bearing surface that faces the magnetic storage medium;
- a second writer having a pole tip with a trapezoidal perimeter along the air bearing surface, the first and second writers adapted to concurrently program different data bits with separate magnetization coils wound about the first and second writers, respectively;
- and
- a third writer shaped with a substantially rectangular perimeter positioned between the first and second writers.
A transducing head comprising:
- an air bearing surface;
- a first writer comprising:
- a pole tip having a trapezoidal perimeter along the air bearing surface, and
- a second writer comprising:
- a pole tip having a trapezoidal perimeter along the air bearing surface, wherein the trapezoidal perimeter of the pole tip of the second writer is configured as a mirror image of the trapezoidal perimeter of the pole tip of the first writer, the first and second writers each positioned between first and second return poles.
