1. A storage device comprising:
- a controller that controls a first write element to write data to a plurality of alternating data tracks on a storage medium and a second write element to write data to at least one data track interlaced with the plurality of alternating data tracks, wherein the first write element is configured to write data at a first write width and the second write element is configured to write data at a second write width less than the first write width.

Abstract
A storage device includes a transducer head including a first write element configured to write data at a first write width and a second write element configured to write data at a second write width less than the first write width. According to one implementation, the first write element writes data at a first linear density and to alternating data tracks and the second write element writes data at a second linear density and to data tracks interlaced with the alternating data tracks.

13. A storage device controller configured to:
-
write data with a first write element exclusively to a first plurality of alternating data tracks on a storage medium until a first capacity condition is satisfied; and after the first capacity condition is satisfied, write data with a second write element to a second plurality of data tracks interlaced with the first plurality of data tracks. - View Dependent Claims (14, 15, 16, 17)
