Abstract
A storage device includes a storage medium and a storage device controller that selectively varies a value of at least one write current parameter to generate alternating data tracks of variable written track width. According to one implementation, the alternating data tracks of variable written track width are generated with a single writer.
Claims20
Apparatus comprising:
- a storage medium;
- and
- a storage device controller that selectively varies a value of at least one write current parameter to write alternating data tracks of variable written track width on the storage medium.
A method comprising:
- defining a first set of values for write current parameters for use when writing data to a pair of non-adjacent data tracks on a storage medium;
- and
- defining a second different set of values for the write current parameters for use when writing data to a third data track interlaced with the pair of non-adjacent data tracks.
One or more tangible computer-readable storage media encoding computer-executable instructions for executing on a computer system a computer process, the computer process comprising:
- selectively varying a value of at least one write current parameter to write alternating data tracks of variable written track width with a same writer.
