Abstract
Systems and methods for reading data from a magnetic medium are provided. A system for reading data from a magnetic medium includes an electromagnetic head array, where the electromagnetic head array includes a plurality of read sensors. Each read sensor of the plurality of read sensors is configured to sense a magnetic field of the magnetic medium and to generate a signal based on the magnetic field. Circuitry is configured to combine the signals of the plurality of read sensors to generate a resulting signal. The resulting signal defines an effective read width of the electromagnetic head array, where the effective read width is narrower than a read width of any of the plurality of read sensors.
Claims22
A system for reading data from a magnetic medium, the system comprising:
- an electromagnetic head array, the electromagnetic head array including a plurality of read sensors, wherein each read sensor of the plurality of read sensors is configured to sense a magnetic field of the magnetic medium and to generate a signal based on the magnetic field;
- and
- circuitry configured to combine the signals of the plurality of read sensors to generate a resulting signal,
- wherein the resulting signal generated defines an effective read width of the electromagnetic head array, and wherein the effective read width is narrower than a read width of any of the plurality of read sensors.
A method for reading data from a magnetic medium, the method comprising:
- receiving a plurality of signals from an electromagnetic head array, wherein the electromagnetic head array includes a plurality of read sensors, and wherein each read sensor of the plurality of read sensors is configured to sense a magnetic field of the magnetic medium and to generate a signal based on the magnetic field;
- and
- combining the plurality of signals to generate a resulting signal, wherein the resulting signal defines an effective read width of the electromagnetic head array narrower than a read width of any of the plurality of read sensors.
