Abstract
A method according to one embodiment comprises reading servo information from a tape; and positioning a head relative to the tape so that readers in an array are about aligned with selected data tracks on the tape, wherein the track width of an inner reader of the array is greater than a track width of at least some outer readers positioned on two opposite sides thereof and aligned therewith. A method according to another embodiment comprises forming an array of readers, wherein the track width of an inner reader of the array is greater than a track width of at least some outer readers positioned on two opposite sides thereof and aligned therewith.
Claims13
A method, comprising:
- reading servo information from a tape;
- and
- positioning a head relative to the tape so that readers in an array are about aligned with selected data tracks on the tape,
- wherein the track width of an inner reader of the array is greater than a track width of at least some outer readers positioned on two opposite sides thereof and aligned therewith.
A method, comprising:
- reading servo information from a tape;
- and
- positioning a head relative to the tape so that readers in an array are about aligned with selected data tracks on the tape,
- wherein three sets of multiple adjacent readers are present, the readers in a given set having about the same track width, wherein readers in at least two nonadjacent sets have about the same track width which is less than the track width as the set therebetween.
A method, comprising:
- reading servo information from a tape;
- and
- positioning a head relative to the tape so that readers in an array are about aligned with selected data tracks on the tape,
- wherein three sets of multiple adjacent readers are present, the readers in a given set having about the same track width, wherein readers in at least two nonadjacent sets have about the same track width,
- wherein the track widths of the sets progressively decrease from an innermost set of the array to an outermost set of the array.
