Abstract:
A method for reducing off-track pick-up for a disc drive having concentric data tracks and a read head with a first magnetic pole piece and a second magnetic pole piece forming a read gap, and a read element, the method comprising the steps of:disposing the read element in a first separation zone formed in the read gap between the first and second magnetic pole pieces, the read element and first separation zone being positioned over a current data track; providing a second separation zone formed in the read gap between the first and second magnetic pole pieces, the second separation zone being positioned over data tracks adjacent to the current data track; providing a first separation width between the first and second magnetic pole piece for the first separation zone; providing a second separation width between the first and second magnetic pole pieces for the second separation zone, the second separation width being less than the first separation width.
