Claims4
-3. (canceled)
A data storage system comprising:
- an optical pick-up unit configured to read fields of modulated wobble indicative of servo operating mode information from an optical media;
- and
- at least one controller operatively arranged with the pick-up unit and configured to control movement of the media and to control the pick-up unit based on the information read from the media.
A method for operating a servo system having a plurality of operating modes and including an optical pick-up unit, the method comprising:
- reading, from an optical media, fields of modulated wobble indicative of servo operating mode information;
- selecting at least one of the plurality of operating modes based on the information read from the media;
- and
- controlling the pick-up unit based on the at least one selected mode.
