Abstract
Disclosed are hard disk drives (HDDs), and methods for use therewith, that utilize reduced overhead servo fields, thereby simplifying the servo system. Reduced overhead servo fields may be of particular use in HDDs that utilize multi-revolution storage techniques to store data at much higher densities than what is possible for conventional HDDs. The relaxed performance requirements of high-density, multi-revolution drives provides opportunities for reducing servo overhead, thereby potentially further increasing the areal density capability of the magnetic media. Servo overhead may also be reduced by placing certain servo data on flash or other memory off of the media disk rather than in the servo fields written to the media disk.
