Abstract
An embodiment of a data write path includes encoder and write circuits. The encoder circuit is configured to code data so as to render detectable a write error that occurs during a writing of the coded data to a storage medium, and the write circuit is configured to write the coded data to the storage medium. For example, such an embodiment may allow rendering detectable a write error that occurs while writing data to a bit-patterned storage medium.
Claims40
A data write path, comprising:
- an encoder circuit configured to code data to render locatable a write error that occurs during a writing of the coded data to a storage medium;
- and
- a write circuit configured to write the coded data to the storage medium such that the write error may be distinguished from a read error when the coded data is read prior to correction of any error.
A media-drive controller, comprising:
- a data write path, comprising:
- an encoder circuit configured to code data to render locatable a write error that occurs during a writing of the coded data to a storage medium;
- and
- a write circuit configured to write the coded data to the storage medium such that the write error may be distinguished from a read error when the coded data is read prior to correction of any error;
- and
- a data read path configured to recover the coded data from the storage medium.
A media drive, comprising:
- a storage medium configured to store coded data;
- and
- a media-drive controller, comprising:
- a data write path, comprising:
- an encoder circuit configured to code data to render locatable a write error that occurs during a writing of the coded data to a storage medium;
- and
- a write circuit configured to write the coded data to the storage medium such that the write error may be distinguished from a read error when the coded data is read prior to correction of any error;
- and
- a data read path configured to recover the coded data from the storage medium.
A system, comprising:
- a media-drive controller, comprising:
- a data write path, comprising:
- an encoder circuit configured to code data to render detectable a write error that occurs during a writing of the coded data to a storage medium;
- and
- a write circuit configured to write the coded data to the storage medium such that the write error may be distinguished from a read error when the coded data is read prior to correction of any error;
- and
- a data read path configured to recover the coded data from the storage medium;
- and
- an integrated circuit coupled to the media drive.
A method, comprising:
- rendering locatable a write error that occurs during a writing of a data to a storage medium;
- and
- writing the data to the storage medium such that the write error may be distinguished from a read error when the coded data is read prior to correction of any error.
