Abstract
An embodiment of a data read path includes recovery and decoder circuits. The recovery circuit is operable to recover coded data from a storage medium, and the decoder circuit is operable to detect, in the recovered data, a write error that occurred during a writing of the coded data to the storage medium. For example, such an embodiment may allow detection of a write error that occurred while writing data to a bit-patterned storage medium.
Claims38
A data read path, comprising:
- a recovery circuit operable to recover coded data from a storage medium;
- and
- a decoder circuit coupled to the recovery circuit and operable to detect in the recovered data a write error that occurred during a writing of the coded data to the storage medium.
A media-drive controller, comprising:
- a data-write path operable to write coded data to a storage medium;
- and
- a data read path, comprising:
- a recovery circuit operable to recover the coded data from the storage medium;
- and
- a decoder circuit coupled to the recovery circuit and operable to detect in the recovered data a write error that occurred during the writing of the coded data to the storage medium.
