Abstract
Example storage medium servo patterns, data storage devices, and methods to provide servo tracks with multiple servo synchronization or servo address marks per servo sector in a data storage device are described. The data storage device may include storage media, such as magnetic disks, having servo sectors that define servo tracks, where each servo sector has a first servo address mark before the track identifier and a second servo address mark following the track identifier. Which servo address mark is used for processing the servo sector is based on the current servo operating mode, such as write operations versus seek operations.
