Abstract
A storage channel, e.g., for a disk drive system, may asynchronously sample and buffer an entire sector, and then process the buffered sector to recover timing information. The storage channel may operate in an open-loop and utilize an exhaustive search to determine timing parameters. Alternatively, the storage channel may operative in a closed-loop, processing the sector once, and feeding back information obtained during decoding to the timing loop.
Claims82
A method comprising:
- asynchronously sampling a signal, the signal including one or more sectors of data;
- processing a sector to recover timing information;
- and
- re-sampling the sector using the timing information.
An apparatus comprising:
- a timing recovery module to recover timing information from a sector of a signal;
- and
- a re-sampling module to re-sample the sector using the timing information from the timing recovery module.
An apparatus comprising:
- means for recovering timing information from a sector of a signal;
- and
- means for re-sampling the sector using the timing information from the timing recovery module.
A computer program comprising:
- asynchronously sampling a signal including a sector;
- processing the sector to recover timing information;
- and
- re-sampling the sector using the timing information.
A storage system comprising:
- a read head to read data;
- and
- a storage channel to receive said data, the storage channel including
- a timing recovery module to recover timing information from a sector of the data, and
- a re-sampling module to re-sample the sector using the timing information from the timing recovery module.
A storage system comprising:
- means for reading data;
- and
- a storage channel to receive said data, the storage channel including
- means for recovering timing information from a sector of the data, and
- means for re-sampling the sector using the timing information from the timing recovery module.
