Redundant sync fields to improve disk drive read performance |
| abstract |
SUMMARY An apparatus and method for reducing the effects of local temperature rise and other abnormal conditions on a disk drive read operation. An improved format for a data block (300, 400) having first and second synchronization fields (308, 316, 408, 412) for storing a plurality of synchronization patterns; The synchronization fields are separated by a selected distance within the data block. The synchronization pattern of the second synchronization field indicates that when the read channel (160) of the disk drive has failed to synchronize with the synchronization pattern of the first synchronization field, the read channel is used in the data block. Synchronize with the user data. In one embodiment, control information used by the read channel to prepare for receiving the user data is stored in a control field (310, 314) between the first and second synchronization fields. In another embodiment, a portion of the user data is stored in a data field (410) between the first and second synchronization fields. |
