Abstract
A storage device includes a storage medium having a first set of non-adjacent data tracks having a number of super parity sectors and a second set of non-adjacent data tracks interlaced with the first set of non-adjacent data tracks. The number of super parity sectors on a data track of the first set of non-adjacent data tracks is selected based on a distance between the data track and an inner diameter of the storage medium.
Claims28
A storage device comprising:
- a storage media including a plurality of data tracks, the plurality of data tracks including a subset of bottom tracks and a subset of top tracks, wherein at least one bottom track of the subset of bottom tracks includes one or more super parity sectors providing error correction for the at least one bottom track of the subset of bottom tracks, and wherein at least one top track of the subset of top tracks does not include one or more super parity sectors.
A method comprising:
- writing a set of bottom tracks, wherein the set of bottom tracks includes at least one parity sector;
- and
- writing a set of top tracks, wherein each top track of the set of top tracks is interlaced with two bottom tracks of the set of bottom tracks, and wherein at least one top track of the set of top tracks does not include a super parity sector.
One or more processor-readable storage media encoding computer-executable instructions for executing on a computer system a computer process, the computer process comprising:
- writing a set of bottom tracks, wherein the set of bottom tracks includes at least one parity sector;
- and
- writing a set of top tracks, wherein each top track of the set of top tracks is interlaced with two bottom tracks of the set of bottom tracks, and wherein at least one top track of the set of top tracks does not include a super parity sector.
A storage device comprising:
- a storage media including a plurality of data tracks, a data track of the plurality of data tracks including a number of super parity sectors, wherein the number of super parity sectors is selected based on a distance between an inner diameter of the storage media and the data track.
