Abstract
A technique is described for reducing overhead in a magnetic medium utilizing interspersed timing synchronization fields. In particular, a reader reads timing synchronization fields interspersed within data fields of the medium to obtain timing measurements. The reader is separated from a writer by a distance greater than a distance of the reader to traverse a select timing synchronization field. As such, the writer may perform a direct current (DC) write to the medium to suspend transitional write operations while the reader is reading the select timing synchronization field, and/or while the writer is over a unipolar field (e.g., a timing synchronization field).
