Servo design in data storage media

A data storage system comprising:

• a data storage medium having a plurality of circumferential data tracks and a plurality of servo regions, each data track being a contiguous data region, and each of the plurality of servo regions radially extending a distance greater than 100 times a track width of one of the plurality of circumferential data tracks;
• and
• a reading device configured to receive first positioning information from one of the plurality of servo regions before a data operation of one of the plurality of data tracks and to receive second positioning information from another one of the plurality of servo regions during the data operation,
• wherein one of the plurality of servo regions is configured to provide positioning information to the reading device before a data operation of a first subset of the plurality of data tracks and during a data operation of a second subset of the plurality of data tracks.

A data storage system comprising:

• a reading device;
• and
• a data storage medium comprising:
• a plurality of circumferential data tracks, each data track being a contiguous data region;
• and
• a plurality of servo regions configured to provide positioning information to the reading device, each of the plurality of servo regions radially extending a distance greater than 100 times a track width of one of the plurality of circumferential data tracks,
• wherein each of the plurality of data tracks corresponds to more than one of the plurality of servo regions,
• wherein each of the plurality of servo regions corresponds to more than one of the plurality of data tracks,
• wherein the more than one of the plurality of servo regions are configured to provide positioning information to the reading device at discrete times corresponding to a data operation of a corresponding data track,
• wherein the more than one of the plurality of servo regions are configured to provide positioning information to the reading device before and during a data operation of a corresponding data track, and
• wherein one of the plurality of servo regions is configured to provide positioning information to the reading device before a data operation of a first subset of the plurality of data tracks and during a data operation of a second subset of the plurality of data tracks.
