Read head with co-planar readers offset from a third reader

摘要

A combination user data signal is read from two or more inner tracks of a recording medium via a first reader that encompasses the inner tracks. First and second data signals are read from respective first and second outer tracks that surround the inner tracks via second and third co-planar readers that are on a same head-gimbal assembly as the first reader. The first reader is centered between and downtrack from the first and second co-planar readers on the read head. User data is recovered based on the combination user data signal and the first and second data signals.

主权项

1. A method comprising:
reading a combination user data signal from two or more inner tracks of a recording medium via a first reader that encompasses the inner tracks; reading, via second and third co-planar readers that are on a same head-gimbal assembly as the first reader, first and second data signals from respective first and second outer tracks that surround the inner tracks, the first reader being centered between and downtrack from the first and second co-planar readers on the same head-gimbal assembly; and recovering user data based on the combination user data signal and the first and second data signals.
