Claims
- 1. A magnetic servo writer comprising:a single rotating magnetic pickup head for rotationally moving over and writing servo data in a magnetic flat data-storage medium for servo-controlling said single rotating magnetic pickup head wherein said single rotating magnetic pickup head is disabled during a specific range of rotational angular positions when rotating over said data storage medium; and a lateral movement means for moving said flat data-storage medium along lateral directions substantially perpendicular to a rotational axis of said single rotating pickup head.
- 2. The magnetic servo writer of claim 1 wherein:said single rotating magnetic pickup head is provided for writing SYNC data for read channel synchronization for servo-controlling said single rotating magnetic pickup head.
- 3. The magnetic servo writer of claim 1 wherein:said single rotating magnetic pickup head is provided for writing ADM data for providing address mark for indicating data-types following said ADM data for servo-controlling said single rotating magnetic pickup head.
- 4. The magnetic servo writer of claim 1 wherein:said single rotating magnetic pickup head is provided for writing ST IDX data for indicating a first valid data segment for servo-controlling said single rotating magnetic pickup head.
- 5. The magnetic servo writer of claim 1 wherein:said single rotating magnetic pickup head is provided for writing ED IDX data for indicating a last valid data segment for servo-controlling said single rotating magnetic pickup head.
- 6. The magnetic servo writer of claim 1 wherein:said single rotating magnetic pickup head is provided for writing GRAY CODE data for indicating a head number, a sector number, and a track number for servo-controlling said single rotating magnetic pickup head.
- 7. The magnetic servo writer of claim 1 wherein:said single rotating magnetic pickup head is provided for writing SERVO POS data for indicating a relative position of said single rotating magnetic pickup head to a data track for servo controlling said single rotating magnetic pickup head.
- 8. The magnetic servo writer of claim 1 wherein:said single rotating magnetic pickup head is provided for writing DATA & GAP data for indicating an area for containing pre-recorded data for servo-controlling said single rotating magnetic pickup head.
- 9. The magnetic servo writer of claim 1 wherein:said single rotating magnetic pickup head is provided for writing index data for indicating a valid data track segment for servo-controlling said single rotating magnetic pickup head.
- 10. The magnetic servo writer of claim 1 further comprising:a control circuit for controlling said single rotating magnetic pickup head for writing said servo data on said magnetic flat data-storage medium provided only to move along lateral directions substantially perpendicular to a rotational axis of said single rotating pickup head.
- 11. The magnetic servo writer of claim 1 further comprising:a servo pattern layout circuit for controlling said single rotating magnetic pickup head for writing said servo data on said magnetic flat data-storage medium with predefined servo patterns for servo-controlling said single rotating magnetic pickup head.
- 12. The magnetic servo writer of claim 1 further comprising:a derived index control circuit for deriving indices from a fixed index provided on said magnetic flat data-storage medium provided only to move along lateral directions substantially perpendicular to a rotational axis of said single rotating pickup head.
- 13. The magnetic servo writer of claim 1 further comprising:a fixed index and clock track circuit for providing a fix index and a clock signal for controlling said single rotating magnetic pickup head for writing said servo data on said magnetic flat data-storage medium provided only to move along lateral directions substantially perpendicular to a rotational axis of said single rotating pickup head.
- 14. The magnetic servo writer of claim 1 further comprising:a head move circuit for controlling a movement of said single rotating magnetic pickup head for writing said servo data on said magnetic flat data-storage medium provided only to move along lateral directions substantially perpendicular to a rotational axis of said single rotating pickup head.
- 15. The magnetic servo writer of claim 1 further comprising:a medium movement circuit for controlling a linear movement of said magnetic flat data-storage medium along lateral directions substantially perpendicular to a rotational axis of said single rotating pickup head for writing said servo data on said magnetic flat data-storage medium.
