Abstract
A hard disk drive with a disk that has a plurality of data bits. The drive includes a circuit that reads each data bit n times and selects a value for the bit based on a reliability factor. The circuit may select a bit based at least in part on the most frequent occurrence of one of a plurality of values. For example, if more 0s occurred than 1s the bit would be set to 0. The reliability factor may be a ratio of the occurrence of 0s to the occurrence of 1s. A bit can be not selected or deselected if the reliability factor exceeds a threshold value.
