Abstract
In one embodiment of a system and method for positioning a transducer head, the transducer head includes a first group of elements for reading data from or writing data to a set of tracks on a storage medium, and a second group of elements for reading data from or writing data to a set of tracks on a storage medium. A device supplies electrical power to the first group of elements to read data from or write data to a first position on the storage medium, and supplies electrical power to the second group of elements to read data from or write data to a second position on the storage medium different than the first position without coarse movement of the transducer head relative to the storage medium.
Claims20
A transducer head positioning system comprising:
- a transducer head comprising
- a first plurality of elements for reading data from or writing data to a set of tracks on a storage medium, and
- a second plurality of elements for reading data from or writing data to a set of tracks on a storage medium;
- and
- a device for supplying electrical power to the first plurality of elements to read data from or write data to a first position on the storage medium, and for supplying electrical power to the second plurality of elements to read data from or write data to a second position on the storage medium different than the first position without coarse movement of the transducer head relative to the storage medium.
A transducer head positioning method comprising:
- supplying electrical power to a first plurality of elements of a transducer head so that the first plurality of elements read data from or write data to a first set of tracks on a storage medium;
- and
- supplying electrical power to a second plurality of elements of the transducer head so that the second plurality of elements read data from or write data to a second set of tracks on the storage medium different than the first set of tracks without gross movement of the transducer head relative to the storage medium.
A transducer head positioning system for use with a storage medium comprising a plurality of storage positions, the transducer head positioning system comprising:
- a transducer head comprising a plurality of element groups, each transducer element group comprising a plurality of elements for reading data from or writing data to one of the plurality of storage position on the storage medium, wherein the plurality of element groups equals the plurality of storage positions on the storage medium;
- and
- a switching device for switching electrical power between the plurality of element groups so that the plurality of elements read data from or write data to each of the plurality of storage positions on the storage medium without coarse movement of the transducer head relative to the storage medium.
