Compensation for writer crosstalk in a multi-channel tape recording head

A method for compensating for cross-talk while writing data on a magnetic tape, the method comprising:

• determining a direction of current flow to be applied to a first write element on a magnetic head to write first data on a magnetic tape;
• determining a direction of current flow to be applied to each of a plurality of neighboring write elements on the magnetic head to write corresponding data on the magnetic tape;
• comparing the direction of current flow to be applied to the first write element to the direction of current flow to be applied to each of the plurality of neighboring write elements;
• and
• controlling the first write element to write the first data on the magnetic tape in response to comparing the direction of current flow to be applied to the first write element to the direction of current flow to be applied to each of the plurality of neighboring write elements.

A computer-program product embodied in a non-transitory computer read-able medium that is programmed to compensate for cross-talk while writing data on a magnetic tape, the computer-program product comprising instructions for:

• determining a direction of current flow to be applied to a first write element on a magnetic head to write first data on a magnetic tape;
• determining a direction of current flow to be applied to each of a plurality of neighboring write elements on the magnetic head to each write corresponding data on the magnetic tape;
• comparing the direction of current flow to be applied to the first write element to the direction of current flow to be applied to each of the plurality of neighboring write elements;
• and
• controlling the first write element to write the first data on the magnetic tape in response to comparing the direction of current flow to be applied to the first write element to the direction of current flow to be applied to each of the plurality of neighboring write elements.
